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
Open your Task manager, search "sh" procces and kill them. Good luck
Im my case, the solution was to close Visual Studio Code -where I had console running too without noticing-
After closing it all back to normal. Hope this helps someone.
To make life easier (this problems happens quite often) create a file called fixbash.bat
in home directory and paste this:
taskkill /F /IM ssh-agent.exe
When problem occurs just open cmd
and type fixbash.bat
to fix a problem.
Or
Just paste the taskkill command into your cmd
if you don't want to create a script.
Restart your machine.
(The other answers did not work for me. (I didn't try reinstalling. Restarting is probably faster.))
