What version of redhat are you using?

What is the output of:
Code:
cat /proc/sys/kernel/core_pattern

Perhaps the application cannot write to the working directory set at the point where it faults? What do you see in strace?

Well, it says core dumped. Maybe they're just not ending up where you expected.
