Generating a core file

duckie316 · 07-19-2006, 08:54 AM

RHEL 2.4.21-32.0.1
I need to reliably generate core dump files for the purpose of testing ulimit -c and sysctl.conf settings before deploying modifications to the field. I only have the RHEL distribution to work with, so games mentioned in some threads are not a reliable source of cores <grin>.

The plan is that I would be able to generate a core file and test that the ulimit -c numericvalue and the kernel.core_pattern = /somewritable/path of the sysctl.conf is appropriate for our environment.

Thanks in advance

Hi,

This should work:

kill -s SIGSERV <pid>

pid being a running program.

Hope this helps.

Druuna,

Thanks for the direction. It worked but with one typo -or- system difference.

"kill -s SIGSEGV PID" created the core file when I specified the PID of a running script.

Many thanks!

Hi,

That was indeed a type. Sorry about that!

To give you an idea of all the 'signals' that can be used: man 7 signal
