    The idea would be to get a core dumped on your client. Then you can
    fetch it back to your developpment platform and analyse it with gdb as
    Apostolos suggested.

    Of course to get a "juicy" core it would be better you have the source
    that you can compile on debug mode. Also check ulimit is set correctly
    on your client side.
