Since putting a stateful firewall on my Indy, I'm seeing the following
error in dmesg fairly often - I believe whenever a tcp connection is
closed.  Other than filling /var/log/messages, it doesn't seem to be
causing any problems - network connections work fine.

Is this a known problem? Anything I can or should do about it?
