mud is crashing for some reason

[CaSpEr7526]

Ok, I come back after a day of not logging onto my mud (no one else logs on) 
and the mud has crashed and not even rebooted....now...i don't allocate memory 
on a tick or anything like that, so it's not memory going up...is it 
automaticly crashing for some reason becuase no one is logged on? or what, is 
there anyway I can run like gdb on it but not be logged into my shell, so I can 
see why it's crashing, but not have to have my computer running for 2 days...
