I have four Core dump files on my server, sized 15M, 114M, 1.6G and 2.9G. What is stored in these files that can result in such a range in size?

These are old files I'm going to delete, so there is no problem here, but I was curious was is found in them that would result in such a wide range of sizes. Also, what can you use to view the data in these files?

Thank you for the quick reply. I figured it would be the contents of the programs Memory at the time of the crash (like all other Dump files), however I still don't see how I got one that is 2.9G. The server only has 1G RAM, I suppose that if the mailserver process was taking 100% of physical memory and 100% of Swap memory then it would add up to 2.9G But I've never seen the server use up that much memory (It wouldn't leave anything for all the other processes on the server).

Perhaps I'll never know, but I'll accept any logical reasons.

Swap file/partition size isn't always exactly twice the size of the physical memory. It's just a recommendation and ultimately set when you tune the installation (you do that, right?). It can be larger and it can be smaller. If you have an application leaking memory, more than one CPU core, a weird memory page size or a mix of 64- and 32-bit software (or some combination of these), the total memory can grow beyond 2x physical memory.
