Re: [Condor-users] condor_rm not killing subprocesses

It seems that your condor setup doesn't give a time to a program to
finish nicely when condor is evicting it - look at KILL expression.
Usually Condor first tries to kill with SIGTERM, and then when KILL
expression is true - it will kill with -9. It seems that bash doesn't
have a chance to clean up all its processes, which it does when you kill
with Ctl-C.
You may also want to specify kill_sig=SIGQUIT, which will cause Condor
to kill it with SIGQUIT first.
