I have had up to 8 git bash terminals running at the same time before.
Currently I have only 2 up.
I have not seen this error before and I am not understand
On a more recent version of git for windows, the process to kill in task manager was "GitExtensions.exe". Killed that and the terminals restarted with no issues.
Found a similar issue and solution in google groups
I opened a windows command prompt and ran the command
$ tasklist
It looks as though the ssh connections I had made in my git bash shells weren't being closed when those windows were closed and were hanging the available git bash shell windows.
This may be a dangerous solution but from the windows command prompt I ran
$ taskkill /F /IM ssh.exe
Everything appears to be working again after this. It may not have directly been an issue of orphan processes, but this worked for at least for me.
Additional note: you can also kill other processes, for example like:
$ taskkill /F /IM vim.exe
Reinstalled git, it is now working fine.
i found that killing msys2 terminal in task manager solves the problem
Open Task manager, find bash.exe process and kill it. Helped in my case.
In system bash type:
ps
Kill any bad looking process:
kill -9 <ID>
Worked for me.
