Hi Reindal,
Apologies if I the subject is misleading.
I meant that when the main process in the service gets crashed, ExecStop
doesn't get invoked. In the below example, I am killing the main process
'CcspCrSsp' and expect the path '/tmp/CcspCrSsp_Restarted' to be created.
However, it is not getting created. Please let me know if my expectation is
correct or ExecStopPost is the right way to handle it.

your subject "ExecStop doesn't get called when service crashes" simply makes no
sense at all then because that's what a failed case is
