kernel : Possibly unexpected TUX-thread exit(11) at c0108658?

Hello,

I am running TUX with a TUX module.
I have been testing the module for days with over 40 millions of random
requests and I never could get to crash the server nor the TUX module I
wrote.
Since my module is online, it does crash often.
I get this message in /var/log/kmessages :
kernel : Possibly unexpected TUX-thread exit(11) at c0108658?
It is always the same address! How could I know where it actually crashed?

When I have a closer look at the system, I can notice that all [TUX worker
0] processes are gone and the [TUX manager] process too.
All there is left, is the [TUX logger] and [TUX date] processes.
The tux log file doesn't tell much about any potential bad incoming request.

When it happens, I just need to do a simple :
/etc/init.d/tux stop; /etc/init.d/tux start
to get the server up and running again.

Does anyone have an idea where this kind of problem could come from?

Thank you in advance for any advice!

Tristan.
