THanks

Core files as I understand them are like a snapshot of the last few seconds of youre muds life just before a crash. They are meant to be used to figure out whatever nasty thing happened to crash youre program. If youre mud is stable and isnt crashing all the time then these are prolly old and more or less useless and can safely be deleted.

And.. um.. if you have several of them... hehehe... I'd say it's time to go hunting for bugs *g*

Oh, a note.. how to use them?

Only problem with using them to hunt things down is that they won't be of much value if any new code has been compiled in since they were generated. Might as well just delete them. You should also get your sysadmin to configure it so that cores don't have the process number attached. Other less dilligent mud admins on the same system could end up contributing to a full disk, which isn't pretty
