Hi

I am getting segmentation fault error but no core dump file is generated on a server i am just supporting, it is running Linux 2.6.9-89.0.25.ELsmp x86_64 GNU/Linux

ulimit for coredumps is set to unlimited, value of /proc/sys/kernel/suid_dumpable is set to 1 and a special directory with RWX permission to everyone is specified in kernel.core_pattern but still no core dumps are being generated when the process is crashed.

The strange thing is i did get a core file for another process when it crashed but no core files for this specific process which crashes quite regularly.

Can anybody help me in this.

regards,

If you have the source for that process can you run GDB on it?

Unfortunately I don't have the source code for this. Is there any other way of generating core dump.

Does this help?

I have passed the case to third line support. So easy now they have to identify that what is wrong with the process

I request you to post the solution you get from the third party support, here. It might help someone else.
