A dynamic firewall rule with a timeout that's to short might cause this. I've also had problems with firewalls that leaked memory, and basically just reset everything at random times. Since I was the only person who left open connections through the firewall, as well as the only person who's desktop wasn't Windows, I was the only person who noticed more than an occasional hiccup. http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
