tux dies when using a module

hi there.

i've been using tux successfully on a production web server for about
two months. recently i wrote a simple tux module, similar to demo2.c,
that serves files based on whether or not the browser has a particular
cookie set. the purpose is to protect proprietary files, without
rewriting all of apache's htaccess into tux.

anyway, the module worked fine on my test server, but as soon as i ran
it on our busy production server, one of the worker threads sucked up
99% of the CPU, and tux became useless. it was then impossible to kill
any of the tux processes. i had to reboot the machine for it to return
to sanity.

when the machine came back up, i found this in /var/log/messages:

Oct  2 00:58:07 sg1 kernel: Process tux (pid: 2068, stackpage=df649000)

Oct  2 00:58:07 sg1 kernel: [<c01d6e22>] sys_tux [kernel] 0x22 

any idea where i should start? i can't reproduce the problem on my
test server, which is an exact clone of the production server. i'm
running redhat 7.3 and the latest rpm of tux.

any help that anyone can provide would be greatly appreciated.
