NoCat crash

I haven't been able to track down what's going on here.  My system is a
dual homed linux router running Fedora 6.  My primary firewalling is
done by shorewall.  I run splashd as a backgrounded, unattached service
via the command:

   nohup /usr/local/sbin/splashd &

Frequently, splashd will crash.  The most recent output was:

After every crash it takes about 2 minutes before I can start the
service again.  The error it displays during this period is:

** ERROR **: bind failed on 0.0.0.0: Address already in use.


Let me know if I can provide more data.  TIA.
