1) Resource limits. Do a 'ulimit -a' and check.
2) File permissions. Can the user the application is running in write
to the directory the application runs in? Is there a 'core' file already
there that the user can't delete or write over?
3) Security considerations. Is the program suid/sgid?

Howdy,
Some of my programs dump core, others don't. I tried
it on RedHat 6.1 and Mandrake 7.0 with kernels 2.2.14
and 2.2.15. I tried tcsh and bash with coredumpsize
set to 1GB. It seems to be application specific.
Is there any other criteria when suppressing apart from
the type of signal and the size limitation?
The application that doesn't dump core contains signal
handlers for some signals, but not for SEGV or ABRT.
