I have the newest (2020.3 EAP ATM) version of CLion and I currently use it to remote debug a program on an embedded target (linux-mipsel).
Everything works as expected, after a bit of configuration, using self-built cross-toolchain and gdbserver.
My only problem is hitting the "red square" to stop execution will neither kill the running program nor gdbserver itself.
This means next iteration of edit-compile-debug cycle I will have two copies of both (I can get more, if I insist) which will not work as each tries to open the same resources (e.g.: a serial port) concurrently.
I have to manually log into target and kill the offending processes.
Am I missing something, is it a known bug or what?
Small update:
gdbserver is actually killed (does not show in ps ax) but underlying program (debugee) is still there. I am unsure why I was convinced otherwise, my bad.
This is a known issue and will hopefully be fixed soon.
Here is the link to the youtrack issue: https://youtrack.jetbrains.com/issue/CPP-20346
You could try the suggested workarounds:
Add pre-deploy configuration which kills running instances of the program
Follow the instructions for the gdb configuration in the comments:
GDB Server: /bin/bash
GDB Server args: -c "gdbserver :1234 /home/pi/myapp; pkill -e myapp"
The second config did not work for me, so I added the execution of an external tool where I run in /bin/bash the command -c "pkill -e myapp || true". The true is mandatory to avoid errors if the program is not running.
My computer kept rebooting lately showing me the blue screen while I was working on RHEL 'n vmware.
The last time the computer had reboot when I turned it on again and tried to work on RHEL here's what I have.
Did anyone of you face the same problem already ?
Thanks
In essence, the error is:

But the thing is when I start the rescue mode I ve that error message :
You don't have any Linux partitions.
When building a Docker image, there's some compilations of C++ scripts and I ended up with errors like:
src/amun/CMakeFiles/cpumode.dir/build.make:134: recipe for target 'src/amun/CMakeFiles/cpumode.dir/cpu/decoder/encoder_decoder_state.cpp.o' failed
virtual memory exhausted: Cannot allocate memory
But when building the same .cpp code on the host machine, it works fine.
After some checking, the error message seems to be similar to the one that people get on a Raspberry Pi, https://www.bitpi.co/2015/02/11/how-to-change-raspberry-pis-swapfile-size-on-rasbian/
And after some more googling, this post on the Mac forum says that:
Swapfiles are dynamically created as needed, until either the disk is
full, or the kernel runs out of page table space. I do not think you
can change the page table space limits in the Mac OS X kernel. I have
not seen anything in all the years I've been using OS X.
Is there a way to increase the swap space for Docker build on Mac OS?
If not, how else can be done to overcome the "virtual memory exhausted" error when building a Docker image?
That does not seem trivial to do with XHyve.
As stated in this thread
I think the default size of the VM is 16GB. I kept running out of swap space even after bumping the ram on the VM up to 16GB.
Check if the method used for a VirtualBox VM would apply in XHyve: see "How to increase the swap space available in the boot2docker virtual machine?"
boot2docker ssh
export SWAPFILE=/mnt/sda1/swapfile
sudo dd if=/dev/zero of=$SWAPFILE bs=1024 count=4194304
sudo mkswap $SWAPFILE
sudo chmod 600 $SWAPFILE
sudo swapon $SWAPFILE
exit
Check also this Digital Ocean Setup, again to test in your XHyve context.
mkswap is also seen here or in docker-root-xhyve/contrib/makehdd/makehdd.sh.
Since you have enough available memory in your host, I recommend you to assign more memory to the Docker VM that is behind.
As stated here:
As I can see that you are on OSX, which runs docker over a Linux VM. Configure the max memory clicking the whale icon in the task bar. By default is 2G.

I recently reinstalled Cygwin on my computer in order to get access to several command line elements that I was missing. I have never had previous difficulty with Cygwin, but after this reinstallation, an error message continues to appear after (almost) each command entered. For instance:
-bash-4.1$ wc m1.txt
3 [main] bash 2216 child_info_fork::abort: data segment start: parent(0x26D000) != child(0x38D000)
-bash: fork: retry: Resource temporarily unavailable
2013930 4027950 74968256 m1.txt
Generally, the command still runs (as seen above), but not always. Occasionally, the 'error' message occurs several times in a row (the initial number "3" will then change to a "4" or "2", notably if I start a second Cygwin window.
Also, as soon as I start up Cygwin, I get the following message before the prompt:
3 [main] bash 6140 child_info_fork::abort: data segment start: parent(0x26D000) != child(0x36D000)
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: Resource temporarily unavailable
-bash-4.1$
At the moment, I am debating whether to uninstall/reinstall Cygwin again or just live with the error messages, but I was curious if there might be an issue that I am unaware of.
(assuming Cygwin is installed at C:\Cygwin):
Open Task Manager and close any processes that look to be Cygwin related.
Open C:\Cygwin\bin in Windows Explorer
Verify that dash.exe, ash.exe, rebase.exe, and rebaseall exist in this folder
If any of them are missing, re-run Cygwin setup and select the dash, ash, and rebase packages
right-click your C:\Cygwin folder, uncheck Read-only (if its checked), and press OK.
When an error about not being able to switch some files comes up, select "Ignore All". Wait for this process to complete.
Browse to C:\Cygwin\bin in Windows Explorer
Right click dash.exe and click "Run as Administrator". A command Prompt should appear with nothing but a $
Type /usr/bin/rebaseall -v, hit enter, and wait for the process to complete.
If you get errors about Cygwin processes running, try Step 1 again. If that still doesn't work, Restart your computer into safe mode and try these steps again.
A commenter noted that, depending on your settings, you may have to type cd /usr/bin && ./rebaseall -v instead.
Try opening Cygwin again.
This process worked for me. I hope it works for you guys too.
Source: http://cygwin.wikia.com/wiki/Rebaseall
I would like to add the following to the above answers, as it is what I had to do after reinstalling Cygwin:
Navigate to the "/usr/bin" directory (usually, C:\cygwin\bin) and right click, Run as Administrator the file: dash.exe
Then, at the $ prompt type the following, hitting enter after each line:
cd /usr/bin/
/usr/bin/peflags * -d 1
/usr/bin/rebaseall -v
What it does is, it marks the dll's as "rebase-able," and then rebases them. You have to have peflags.exe in addition to the above files (in previous answers). You may have to restart windows after doing this and you will definitely need to make sure that there are no processes nor services belonging to cygwin running. (Use task manager, kill any related processes, and then under the services tab look for any service starting with CYG and stop it.)
After doing this, I was able to get cygwin to run without any errors about dll's being loaded to the wrong addresses aka fork errors, etc.
I hope that this helps others, as it was a pain to find.
SOURCE: http://www.cygwin.com/faq.html#faq.using.fixing-fork-failures
and the rebase README file.
To add on to other answers here, we ran into the same issue but could not run the rebase command from the ash or dash shell. However, when launching the command from the Windows cmd shell, the following worked.
cmd /c "C:\cygwin64\bin\ash.exe /usr/rebaseall -v"
-v is to get verbose output
I found another information here :
http://cygwin.com/ml/cygwin/2014-02/msg00531.html
You have to delete the database at
/etc/rebase.db* and do in a "ash" windows :
peflags * -d 1
rebaseall
It works for me on 2 servers.
I solved this problem by restarting my computer. Probably installed a driver update and kept using sleep instead of shutting down.
Experienced the same issue when loading Cygwin with cygiconv-2.dll forking and not loading successfully in the Cygwin terminal, but after turning off my AntiVirus (it was specifically Ad-aware), the issue resolved, and Cygwin worked properly.
In case you are using babun's Cygwin, after rebaseall, try launching Cygwin by executing .babun\cygwin\cygwin.bat in a Windows command prompt or Windows explorer.
This works for me (while launching babun's default console - mintty results in fork error).
I had the error on win10 and i was trying to rebase to c: before install.
then i saw that the installer was installing it instead to c:/Users/myuser
so i was coping all files from c:/Users/myuser to c:.badun
and then restart plus open badun.bat
not shure if this was wise its now duplicated XD... but then it worked again.
Rebaseing didn't help in my case. In addition to what other people suggested, I noticed that reducing the length of PATH environment variable fixed the issue for me (and for other people as well as can be seen from this answer).
This issue is intermittent in nature & I found this issue when there is network is too slow to connect to remote machine on AWS.... I have Shell script that runs through Gitbash shell & it connects to AWS EC2 instance with ssh..... Most of the time, it ran correctly but 2 out 100 times it get into this issue bash: fork: retry: Resource temporarily unavailable .... Killing the MSYS2 terminal from task manager helps to overcome with this issue....
Negative side is you need to run the scripts from the beginning...
I had the same issue on Windows 10 and the mobaxterm app (which uses cygwin) and I tried all of answers listed here however for me, the solution was to simply delete the "CryptoPro CSP" application.
I started facing this problem after upgrading to windows 10. As of now I do not see that any of the above method working.
What I am noticing is that if you start cygwin with admin right (right click and say "run as admin") then it works fine.
Or you open cmd as administrator and then launch cygwin from there, then also it runs fine.
Just reinstall cygwin and select TCL and activate EXPECT
I've got problems installating the VMWARE ESXi Server.
The Installation finishes without any error messages and prompts me to reboot.
After pressing Enter the System reboots. While booting through the yellow loading-screen it switches to black and displays the following Error-Message:
PANIC: Failed to find HD boot partition
All modules have been loaded without any errors.
After typing unsupported into the console the busybox comes up.
I tooked a look into the /dev/disks directory but no disk devices gets listed in difference to the installation process.
Switching to the system-console during installation both sata disks on MPC51 controller are shown.
The controllers are named vmhba0 and vmhba32.
Does anyone know how to solve the problem?!
Hardware is a ESPRIMO P5615 (nForce4) from Fujitsu-Siemens.
The only solution I have found is to run the server from a thumb drive and use the embedded hard drive to store your virtual servers. This solution worked for me.
To achieve this in this way you will need:
A USB thumb drive 1GB or larger
An active Linux machine (or, use a liveCD option on your PowerEdge such as Knoppix or Gentoo LiveCD)
Mount your ESXi ISO:
mount -t iso9660 -o loop VMware-VMvisor-InstallerCD-3.5.0_Update_2-110271.i386.iso /mnt/esx
Write the installer file to the thumb drive:
tar xvzf /mnt/esx/install.tgz usr/lib/vmware/installer/VMware-VMvisor-big-3.5.0_Update_2-110271.i386.dd.bz2 -O | bzip2 -d -c | dd of=/dev/sdb
Assumptions here (adjust to your settings):
/dev/sdb is where your thumb drive resides
VMware-VMvisor-InstallerCD-3.5.0_Update_2-110271.i386.iso is the name of your ISO file
usr/lib/vmware/installer/VMware-VMvisor-big-3.5.0_Update_2-110271.i386.dd.bz2 is the name of the dd file in your iso (run tar ztf /mnt/esx/install.tgz to see what your exact file name is, it should be similar and relatively obvious)
It will take a few minutes to write, and when it's done simply boot off of this thumb drive. The PowerEdge servers have an internal USB (at least mine does) if aesthetics are important to you.

EDIT 12/19/2009: ESXi 4.0.0 uses image.tgz instead of install.tgz to store it's dd file
