How to core dump of daemon process on linux

[snav]

Hi,
I am using a server application running as daemon process, which gets crash after some time( 2 days), To identify the root cause area, i am to take the core dump of this daemon process.

I am able to core dump of any user application(debug binary). But i am not able to debug the Daemon application( i have build this application in debug mode).
Please help to resolve the issue.

Machine-> RHEL 5.3

Thanks
ND

To enable dumps for every daemon:

ulimit -c unlimited >/dev/null 2>&1 (-c maximum size of core files)
ulimit -S -c ${DAEMON_COREFILE_LIMIT:-0} >/dev/null 2>&1

Dump for system:
DAEMON_COREFILE_LIMIT='unlimited'

The same for every daemon (in /etc/sysconfig/_daemon_): DAEMON_COREFILE_LIMIT='unlimited'

Dump for SUID programs:
echo 1 > /proc/sys/kernel/suid_dumpable

In /etc/sysctl.conf:
kernel.core_uses_pid = 1
kernel.suid_dumpable = 1

and sysctl -p
