For the last year it has been working well enough that it doesn't require a reboot to start working again. I read in problem kern/91000 that the sk watchdog timers should be gone, so I tried it out. They are still present for me. This causes loss of connectivity long enough to reset a putty session (and require "Duplicate Session" to log back in.) I can run any tests required or requested. >How-To-Repeat: I can not make the problem fail. It seems to happen during use (while using putty or using squid as a cache.) It does not appear to damage outbound ssh connections (so my ssh commands inside screen to other machines rarely get disconnected.)
