Core file not getting generated!!

Some strange behavior.

Process is receiving Segmentation Fault. But no core files getting generated.

I have checked ulimit.

coredumpsize = unlimited.

In console, process is printing Segmentation Fault even through gdb also same behavior But No corefile.

Any possible reason ?

Did you issue the following command before running the process which generates segmentation fault?

ulimit -c unlimited or any size

Yes, I have started process after setting ulimit to unlimited.

It happend sometimes on same system not able to identify exact scenerio.

I am using Suse 64 bit.

I am using linux system and it always working for me.
