I am at my wits end on this and can't figure this out. In sitecore v6.2 something has changed that is causing an error message as follows
"The operation could not be completed. Your session may have been lost due to a time-out or server failure".
looks like this is coming from Sitecore.Web.UI.Sheer.ClientPage?
The request info:
https://sitecore.test.domain.com/sitecore/shell/sitecore/content/Applications/Content%20Editor.aspx?ic=People%2f16x16%2fcubes_blue.png
the response:
{"commands":[{"command":"Alert","value":"The operation could not be completed.\n\nYour session may have been lost\ndue to a time-out or a server failure.\n\nTry again."}]}
At first, I assumed it was because plugged in some new HttpModules so I moved them into the sitecore pipeline model and the problem kept persisting. I removed them from the entire application and the problem kept persisting.
A google search on the error gets me to some information on the keepalive.aspx stuff, but addressing that has no bearing.
I decompiled the code with reflector, but can't find anywhere this particular error is raised. It must be in sitecore.nexus or something.
According to my superiors we will open a ticket once we get the build resolved, but here's to hoping someone here has some suggestions.
The constant for this error message is THE_OPERATION_COULD_NOT_BE_COMPLETED_YOUR_SESSION_MAY_HAVE_BEEN_LOSTDUE_TO_A_TIMEOUT_OR_A_SERVER_FAILURE_PLEASE_TRY_AGAIN
This might happened if you server restarts while some dialog opened

I have made a flutter app which gives notifications whenever I get an error on the machine running embedded. The way I achieved this is by posting the error on the hosted webserver's page every time I have an error, and then the moment the error is resolved, removing it from the page. Meanwhile, the flutter app connects to this webserver page via the ip address using http request and then refreshes it every second to see if there is any data. If there is, then it sends a notfication on the phone, and starts comparing the data every second to see if any change happens. If the data is changed, another notification is sent else it keeps on refreshing the page and reading it.
The program I used to write the error to this webserver is through C++ code which opens the index.html file, performs write operation and then closes the file every time a new error occurs. The moment, the error is resolved, the file is again opened and the record is deleted making the index.html blank and ready to receive another error.
I want to know if there is any better way to achieve this so that the page only refreshes on new data arrival. As I have been told, refreshing the webpage every second can cause extra pressure on the embedded processor it has been hosted on. Any leads will be appreciated.
Thanks for your time ^^.
On Windows when I execute:
c:\python35\scripts\tensorboard --logdir=C:\Users\Kevin\Documents\dev\Deadpool\Tensorflow-SegNet\logs
and I web browse to http://localhost:6006 the first time I am redirected to http://localhost:6006/[[_traceDataUrl]] and I get the command prompt messages:
W0913 14:32:25.401402 Reloader tf_logging.py:86] Found more than one graph event per run, or there was a metagraph containing a graph_def, as well as one or more graph events. Overwriting the graph with the newest event.

When I try http://localhost:6006 again, TensorBoard takes a long time presents the 404 message again but this time displays a blank web page.

Why am I getting redirected and 404ed?
i'am having the exact same error. Maybe it is because of this issue. So try to Change the env-variable to --logdir=foo:C:\Users\Kevin\Documents\dev\Deadpool\Tensorflow-SegNet\logs.
Hope it helps.
Could it be that you try to access the webpage with IE? Apparently IE is not supported by Tensorboard yet(https://github.com/tensorflow/tensorflow/issues/9372). Maybe use another Browser.
I encountered the same error before, and found that it was due to internet setting problem.
On Internet Explorer, Go to Tools -> Internet Options -> Connections, click LAN settings, and then click Automatic detect settings.
Running CF builder 3, Help > Check for Updates throws an error -- "Unable to read repository at http://ahtik.com/eclipse-update/content.xml.
peer not authenticated". Not sure why it's looking there, but I pasted the url in browser and indeed got a 404 error. Is there a way to change where CFB looks for this update check?
Okay, I was getting the "No repository found at file:/Y:/.." message because the path was listed under window > preferences > Install/Update > Available Software Sites. Y was a network drive that we disabled, but beyond that, it looks like my CFB was incorrectly configured for updates anyway. I spent some time trying to add in the standalone patch at the top of https://helpx.adobe.com/coldfusion/kb/coldfusion-builder-3-updates.html, but kept getting error messages. I inherited this copy of CFB a year ago, so I just did a clean reinstall. After that did Help > Check for Updates, it found and installed an update, restarted CFB, and now everything's good.
Ever since upgrading to CF10, we've been having some odd issues with our automated ColdFusion emails. The processes always functioned properly in the past, but lately we've been getting some very out of the ordinary issues which I'll describe further below.
We discover the problem usually from contacts who usually receive these emails on a daily basis with or without attachments. We'll go to the CFMAIL directory for the corresponding server and find a slew of emails stuck in the 'Undelivr' emails. In some cases, we can just move these emails to the Spool folder and they process fine, but in most cases they result in one of the two errors below:
Error 1: In an email which normally does not contain a body and contains an attachment, the follow error is what we found in the logs:
"Error","scheduler-1","01/15/13","14:09:56",,"javax.mail.MessagingExce ption: missing body for message"
javax.mail.MessagingException: missing body for message
at coldfusion.mail.MailImpl.createMessage(MailImpl.java:696)
at coldfusion.mail.MailSpooler.deliver(MailSpooler.java:1295)
at coldfusion.mail.MailSpooler.sendMail(MailSpooler.java:1197)
at coldfusion.mail.MailSpooler.deliverFast(MailSpooler.java:1657)
at coldfusion.mail.MailSpooler.run(MailSpooler.java:1567)
at coldfusion.scheduling.ThreadPool.run(ThreadPool.java:211)
at coldfusion.scheduling.WorkerThread.run(WorkerThread.java:71)
Placing these emails that have always been sent out this way in the past without an attachment in the spool directory causes it to go right back in the 'Undelivr' folder and resulting in the same error. We ended up having to modify the email file and add random content in the body message, place it back in the spool directory, and it went through. - Mind boggling.
Error 2:
"Error","scheduler-2","02/04/13","09:08:17",,"javax.mail.MessagingExce ption: Exception reading response; nested exception is: java.net.SocketException: Connection reset"
Both errors occur randomly and we have not been able to find out what causes them randomly from time to time. All other emails go through fine, but certain emails will never go out and end up in the 'Undelivr' folder.
We are running them on Windows Server 2008 64bit.
I was facing second error connection reset couple of week ago but that was in CF9 and with SSL only. Here is blog post if that help

I've created a command in the Sitecore Editor that automatically builds out up to 25 items at a time. The problem that I'm experiencing is that the operation just "hangs" and does not complete. I don't think it's an error because I've added error handling and logging.
I'm getting the following error message "The operation could not be completed. Your session may have been lost due to a time-out or a server failure. Try again."
How can I increase the "time-out" duration (if this is a setting somewhere) - or is there another solution to this problem?
Long running operations will time out eventually depending on your IIS settings, usually after 20 mins. Instead, you should run your commands as a scheduled task, as they run in the background, with no waiting for the IIS request.
However, it seemes strange that inserting 25 items is such a long operation that the browser times out. You might have another issue in your code.
