Ok, I tried setting ulimit to unlimited inside the script. This didn't help,
still no core dump
I did get logging working though:
/usr/bin/postmaster: CleanupProc: pid 20146 exited with status 139
Server process (pid 20146) exited with status 139 at Tue Jan 23 22:32:26

Terminating any active server processes...
Server processes were terminated at Tue Jan 23 22:32:26 2001
