We have been experiencing a problem for the past few months where (sometimes) when we restart Jenkins we must save the System Configuration on startup or builds won't work. The builds will generally fail due to not finding the Git executable for the job as if the Git tool version is not defined (even though it is) or the JAVA_HOME or other random environment variables not being set. Saving the system configuration fixes these issues.
Does anyone know how I can even begin to debug this issue?
