Once, on a smoothwall where there was a bug with the MMS (multimedia) kernel
modules. I disabled them (rmmod) and the firewall seemed to work fine after. I
replaced it because it was on our main gateway, so don't know if there were
other issues, or if the bug has been fixed. It would spontaneiously reboot
after a time, or if certain types of multi-media were streamed. Annoying.
