Server is really unstable

[Derision]

As you are running Linux, you are well placed to try and track this down.

In a command prompt, before you run the script to start your zones, issue the command:

ulimit -c unlimited

to enable core dumps.

Run eqlaunch to start the zones, then when you get a crash, you will have a file called core or core.nnnnn (where nnnnn is a number) in the same directory as your zone executable.

Next fire up gdb in the same directory with the zone executable and the core dump

gdb ./zone <core dump file name>

At the (gdb) prompt, issue the command bt full. This will display a backtrace of the sequence of calls that lead up to the crash. You can copy and paste that here.

e.g.

Core was generated by `./zone dynamic_01 zones'.
