I'm seeing errors in StackDriver logging for my Compute instance. The logs are showing repeated issues every hour, creating a lot of noise. I have a Spring Boot API deployed in a container to a VM in Compute Engine using latest stable version of Container OS.
I'm relatively new to GCP and don't understand what is causing this issue, searches have come up empty so far.
Failed to call method: org.chromium.SessionManagerInterface.RetrieveActiveSessions: object_path= /org/chromium/SessionManager: org.freedesktop.DBus.Error.ServiceUnknown: The name org.chromium.SessionManager was not provided by any .service files
CallMethodAndBlockWithTimeout(...): Domain=dbus, Code=org.freedesktop.DBus.Error.ServiceUnknown, Message=The name org.chromium.SessionManager was not provided by any .service file
Error calling D-Bus proxy call to interface '/org/chromium/SessionManager': The name org.chromium.SessionManager was not provided by any .service files
The same 3 lines are repeating every hour. Anyone aware of what might be causing this or how to fix/suppress these?
I looked into this error, and as per my findings:
The error message that you have been receiving is a manifestation of Chrome to reliably exit shortly after starting up.
The UI’s job (which encompasses Chrome, the session_manager and the window manager) gets shut down by upstart because of it's thrashing, and when the test tries to restart the session_manager, the session_manager cannot communicate it over to the D-Bus.
The crash collection software in Container OS was originally for Chromebooks (The laptop using Chrome browser). So the code typically expects Chrome and some other related software on the system.
However, Container OS is a server OS, and does not have Chrome. So if Chrome is missing, the software will report some errors. They are actually not real failures, just some verbose error messages.
Overall, It is safe to ignore these logs and continue using your VM Instances.
Hope this helps.

I had installed ColdFusion 2018 recently and with the installation less than a month old (and my understanding of the technology even less), my Cold Fusion service has stopped working. I have tried a number of things and have referred to a number of articles and out of many such errors where the service is not being accessible, some of them were able to get it resolved. However, some other obscure reason that may be causing this error have been untouched and unknown.
Whenever, I try to restart the service, I get an error as shown below:
Windows could not start the ColdFusion 8 Application Server on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to server-specific code error 2.”
Without much understanding, I started to google it out. Looking into every one of these posts, I tried
Configure JRE and try to relaunch the service by looking at "JAVA_HOME" variable and JVM.config
Run the batch files in every possible combination to find if anything clicks
Check if the present JAVA version works and is compatible with Coldfusion version installed
Fiddling with the "SessionStorage" var in neo-runtime.xml file as some suggested
and few other tricks coupled with a numerous service restart attempts and a few machine reboots as well.
A service that renders Cold Fusion pages should be shut down abruptly. To add to agony, the CF Admin also depends on the service and hence does not work.
Any pointers to any potential solutions?
I have a problem with a web service that is installed and started with a .msi that is created with the WiX toolset.
The service can be installed and started on all the machines I tested so far (shown as running in the Services Manager) but on some machines it is not reachable (for example via a browser) and not shown in the list of listening ports on that machine (displayed with 'netstat -a').
I am trying to figure out what's going wrong but I am not really familiar with web service development and configuration. It's a third party service, thus I don't know how it works internally.
A good starting point for me would be to find out, what exactly happens when a service is installed and started during the execution of the .msi-file.
Maybe I could try to tackle the problem on a lower level then.
Below is my code in the ServiceInstall-Element:
<ServiceInstall
Id="ServiceID"
Type="ownProcess"
Vital="yes"
Name="ServiceName"
DisplayName="ServiceDisplayName"
Description="Lorem Ipsum"
Start="auto"
Account="LocalSystem"
ErrorControl="normal"
Interactive="no"
Arguments="action=run">
</ServiceInstall>
The argument is important - without it, the service won't start or run.
Maybe someone else encounterd the same or a similar problem and can help me out.
Thanks already in advance - each hint is appreciated.
EDIT I (15.04.18):
As it might be a problem with the specific service, I will add some further information here:
It's a third party software called CryptoLicensing:
http://www.ssware.com/cryptolicensing/cryptolicensing_net.htm
Part of this software is that specific program, that serves as a License Server and does the license registration, for example in a customer's network.
The service can be run as a Windows application or installed and run as a Windows service. In both cases it should be listening on a (pre-)specified port on the installed machine.
Whenever I start the .exe as an application, everything works as intended. The service is reachable (for example with the browser) and can be accessed from other machines in the network.
When the .exe is installed and started as a service, it does not work as intended on every machine. For example if I install and start the service on my laptop, it is shown as running in the Services Manager, but is not reachable on its assigned URL (not even on the localhost) nor is the specific port displayed in the active listening ports, for example with 'netstat -a'.
The service itself starts without any error messages and does not log any errors or exceptions as it seems to be running without any problems.
I contacted the vendor, but sometimes he doesn't reply quickly and he is not very specific in his replies.
Before asking the question I assumed that it was a problem with the Windows user rights and the WiX installer but during the discussion here I had the feeling that it might a problem with the service itself.
I hope this 'new' piece of information helps in isolating and location the problem.
Thanks to everyone who helped so far!
Hopefully not stating the obvious here, but WiX doesn't do much except populate the ServiceInstall table in the MSI file, so this is about why Windows Installer won't start the service. ServiceInstall table:
https://msdn.microsoft.com/en-us/library/windows/desktop/aa371637(v=vs.85).aspx
Also, this isn't really about ServiceInstall - it's probably about the ServiceControl element in your WiX source, but it's not clear whether that's how you're starting it or if you're starting it manually later on. That does make a difference. What is the error message and where are you getting it, and is it a 1920 or 1921 error (in the context of ServiceControl).
The main reason a service will start on one system but not another is missing dependencies. If your service is C++ based (the post doesn't say) then there are probably dependencies on C runtimes, UCRT runtimes, MFC or ATL runtimes and so on.
First: are you sure this service is intended to run as LocalSystem? (MSDN, SO).
Second: did you check the event logs in detail for anything obvious? If the service is good you should find a hint at least. Something to start with. I find that I sometimes miss the actual logs in the event viewer because it is so "crowded". My take on it: empty the log and stop and restart the service.
Something locking / blocking: If the service installs and runs OK I would suspect other factors such as firewalls (hardware & software), security software in general (anti-virus, malware scanners), network configuration issues (proxies, WINS, DNS and all the complexities involved in networking). Is the service trying to reach an UNC path?
Diverse Machines: What are the target machines? Are they virtual, are they physical, are they test machines, are they operative SOE machines in corporate networks? Are they the same OS version and edition?
Further Ideas: It is not quite related, but maybe skim this list of suggestions for debugging from another answer (I am not sure why it was down-voted, I think it is an OK list to inspire debugging ideas): Windows Application Startup Error Exception code: 0xe0434352 (maybe just skim the bolded words for ideas - Recommended).
sc.exe: And finally, perhaps check the sc.exe tool (Service Control) and see if it can provide you with some useful information for debugging.
sc.exe in the context of killing hung services (sample use).

Windows Services Frequently Asked Questions (FAQ). Content seems to be up to date - at face value at least. These guys claim to be experts on services. I have no idea who they are.
Essential Tools for Windows Services: SC.EXE
Run Service Control (sc.exe) command on secure port
After almost 20 months we finally (and accidentally) found a solution to the problem! For the few machines, on which the service did not run properly, setting the NoInteractiveServices value in the registry to 0 did the trick. A value of 1 (which is default) means that no service is allowed to run interactively, regardless of whether it has the SERVICE_INTERACTIVE_PROCESS property. More information on Interactive Services.
I am not completely satisfied with the solution, because on all the other machines NoInteractiveServices is set to 1 AND the service runs properly anyway. However, on the machines where the service did not run interactively this solution worked for us. Thus I will accept this as an answer.
If anyone has more information on this issue and can explain why this works, feel free to
add them - I would be very interested!
I have installed hyperledger composer locally. But on localhost it gives error :
Error : Error trying to ping.
Error: No business network has been
specified for this connection.
I am not able to add model and script file as well.
This is the errors showing in terminal
error: [Hyperledger-Composer] undefined:HLFConnection :ping() Error: Error trying to ping. Error: No business network has been specified for this connection
at _checkRuntimeVersions.then.catch (/usr/local/lib/node_modules/composer-playground/node_modules/composer-connector-hlfv1/lib/hlfconnection.js:787:34)

at process._tickCallback (internal/process/next_tick.js:180:9) error: [Hyperledger-Composer] undefined:ConnectorServer :Error: Error trying to pi
I think I solved this problem.
About the error
The error reason is No business network has been specified for this connection., this does not happen when you first time to run composer-playground, because that time, you truly do not have a network and you either do not have card too, so there is a modal pop up Let's blockchain.
This only happened when you stop/delete your business network net, or there is no business network running but you also have the business card linked to the network.
Solution
Follow the tutorial to create a new business network locally
restart your farbric tool by stopFabric.sh and startFabric.sh, (* this is not to start your business network but your fabric)
run your playground again composer-playground
probably you will also see the error again (error trying to ping), but no worry
find a button at top right corner which is folded My Business Networks
delete the card without connection or deploy a new network
This worked for me, hope it will work for you too. This kind of process design limitation, the card is still there even you delete your network or your are trying to start your playground even you did not start your network. This is why this error happened I think.
Addition, More about playground
Hyperledger Composer Playground (Playground from now on) uses your
browser's local storage to simulate the blockchain network's state
storage, which means you don't need to run a real validating peer
network to use Playground.
Using browser-only mode, you can model and test the business network
using a mock blockchain ledger that resides in your browser's local
storage.
How to delete cache in browser Chrome
This probably can solve many errors.
In Chrome, for example, under Settings > Advanced > Content Settings >
Cookies > All cookies and site data > localhost, click the trashcan
icon to remove local storage. If you're using a different browser,
follow the instructions specific to that browser, and delete all local
storage.
References
A very good IBM blockchain/ composer tutorial, just old, need to be pay attention to that some commands not working in the same way on new version of composer
I got the same issue here. I'm not sure what's wrong(maybe because I fail to create a business network last time). But since the playground store the data with browser local storage. I simply clear the local storage and fix it.
I had the same issue and it got fixed.
Clear the cache of your browser and refresh the page!
Noticed composer wasnt running in the terminal.
Runcomposer-playgroundin the terminal and retry.
I am using Coldfusion MX8 server and one of the scheduled task was running from 2 years but now suddenly from 01/12/2014 scheduled tasks are not running. When i browsed the file in browser then the file is running successfully without error.
I am not sure is there any updatation or license expiration problem. I am aware that mid of this year Adobe closed the support for coldfusion 8.
The first most common problem of this problem is external to the server. When you say you browsed to the file and it worked in a browser, it is very important to know if that test was performed on the server desktop. Knowing that you can browse to the file from your desktop or laptop is of small value.
The most common source of issues like this is a change in the DNS or network stack that is interfereing with resolution. For example, if the internal DNS serving your DMZ suddenly starts serving the "external" address - suddenly your server can't browse to your domain. Or if the IP served by the server for the domain in question goes from being 127.0.0.1 to some other IP that the server can't acces correctly due to reverse proxy or LB or some other rule. Finally, sometimes the Apache or IIS is altered so that an IP that previously was serviced (127.0.0.1 being the most common example) now does not respond.
If it is something intrinsic to the scheduler service then Frank's advice is pretty good - especially look for "proxy schduler" entries in the log - they can give you good clues. I would also log results of a scheduled task to a file. Then check the file. If it exists then your scheduled tasks ARE running - they are just not succeeding. Good luck!
I've seen the cf scheduling service crash in CF8. The rest of CF is unaffected.
Have you tried restarting the server?
Here are your concerns:
Your File (works since you tested it manually).
Your Scheduled Task (failed).
Your Coldfusion Application (Service) (any changes here)?
Your Server (what about here).
To test your problem create a duplicate task and schedule it. Leave the other one in place (maybe set your new one to run earlier). Use the same file too. See if it completes.
If it doesn't then you have a larger problem. Since the Coldfusion Server sits atop of the JVM there could be something happening there. Things just don't stop working unless something got corrupted or you got compromised. If you hardened your server by rearranging/renaming the file structure to make it more secure...It would break your task.
So going back: if your test schedule works then determine what is different between the two. Note you have logging capabilities. Logging abilities for CF8
If you are not directly incharge of maintaining this server, then I would recommend asking around and see if there was recent maintenance, if so, what was done to the server?
We have automatically started service which in some cases spends a lot of the time loading necessary data, let's say 10 minutes. During this time it works as expected (processing some huge data files required to start). I report the progess by C++ SetServiceStatus function, it is working fine.
This service is not dependent on anything and has only one dependency which is again our own service. It is started after those 10 minutes, it needs the first "server" service to be fully running to accept the requests.
I thought that windows would start all other automatic services (in less then 10 minutes as usually) and then start working normally but system is completely blocked during startup (i can't login to computer or ping the computer) until this one specific service is started (reports SERVICE_RUNNING by SetServiceStatus). When out service completely starts, the other missing system services (required for network, remote desktop, whatever, it's quite random) are also started. Is this normal behaviour? Why are non-depending processes (as remote desktop, network connections, etc.) waiting for this process? Am I missing something?
I tried to add some dependencies to postpone the startup of my service but I ended up with many dependencies and behaviour still somehow random (as order of services is random). Sometimes I was able to login but for example Start button started working only after those 10 minutes when my service was started. I am not sure what is "the last service" to depend on and what services to include to my depend-list and on some computers this services can be disabled and it can bring new problems... so I don't like this solution very much.
Another option was Delayed start option for our service. This should start service when all other automatic services are running. Well, this works fine, windows boots, computer running and responding, our service is started, but the performance is very bad, many times slower than usually, it seems that delayed started services have much lower priority or something like that.
My only current solution is to report to system that my service is running (by SetServiceStatus function), but to continue loading (this works, I tested it). But then we have problem with our dependent service as it needs to be started when the first one is really ready. It can be solved but I still wonder how is this possible and if there is something I could use to keep the current state of automatic started service which reports "started" when it is really fully started and prepared to work. Thanks for any ideas.
Set SERVICE_RUNNING as soon as possible, and then continue processing in background. Make your other service resilient to the first service being in a running state, but not yet ready to service.
The longer the service is in the starting state the more problems we get from different windows versions.
