You may want to think about keeping the core dumps around so I can log into your server and poke at them with gdb. I tried looking at the relevant sections, but I couldn’t determine what went wrong.

3

how do I generate core-dumps with gdb?

4

I don’t know how to save a core dump from within gdb. If I don’t have the ability to run a program myself through gdb, I have Linux dump the core for me.

ulimit -c unlimited
./gserver_d

The ulimit command will cause it to dump the core. I can then load the core into gdb later on:

gdb gserver_d core.12345

oooh, that’s how you do it. :slight_smile: I shall do that from now on.
