Oracle Linux Server release 6.2
Linux my_hostname 2.6.32-300.3.1.el6uek.x86_64 #1 SMP Fri Dec 9 18:57:35 EST 2011 x86_64 x86_64 x86_64 GNU/Linux

We have custom software (non-oracle) being used to manage our imaging system.When process crashes core dump was not getting generated. I've asked our unix admin to make coredump value unlimited for the userid that is running server process, log out and relogin and double checked with ulimit command and it showed:

 ulimit -a

*core file size          (blocks, -c) unlimited*
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0

max user processes              (-u) 1024
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

From same shell prompt started process and it still did not generate core dumps on the subsequent crash has following message in logfile: Process 2504(cumulusd) has RLIMIT_CORE set to 0 Aborting core

wondering what iam missing here.

Regards,
Sanjeev.
