A core file is a binary file with the state of the world (so to speak) when a program dies. You can force a program to die and generate a core with kill -6 <PID>. You need to make sure your ulimit is setup to allow you to have core files.

You can use gdb to debug a program via a core by by typing "gdb <programexe> <corefile>".

You can also generate a core file from a living application without killing it with the gcore command.
Gcore is only recently available under Gnu/Linux.
