Last restart of the process was from automated crontab script and it was not generating coredump file.
$HOME/.bash_profile has: ulimit -c unlimited command, tested this from command line shell with kill -11 <pid> and it generated coredump. Updated automated crontab script with 'ulimit -c unlimited' command explicitly - will check if this makes a difference again after weekly recycle.

Regards,
Sanjeev.
