core dump

I have been receiving a memory fault/core dump while running a local unix program. I wanted to know if this is a database problem or a unix memory problem and how to fix this.

Re: core dump

There are not enough data to even begin. Your first task would be to use a debugger to examine the core file and do a stack trace. The stack trace will tell you what function/system call actually initiated the dump. A simple "file core" will at least identify the process for you but that's about all it's good for. This could be caused by process limits (e.g. maxdsiz) being exceeded, lack of swap, or much more likely a programming error.
If it ain't broke, I can fix that.
