I am logged in remotely via ssh. I do a tail -f on my news.notice file. (~14 megs/day) It is actually a: tail -f /cnfs/log/news.notice | egrep -v rejecting\\[perl I put it in the background with ^Z for a while. Perhaps 15 or 20 minutes. I then do a fg. As expected, I get a bunch of data scrolling quickly. What is not expected is that after a bit of it, the machine hangs dead and reboots. No kernel messages logged. I'm guessing it is a panic, but I have never been around to put a console on it and look. (erm... not that I ever think "oh, I am going to crash this machine" before I do it...) This has happened twice. Ideas? I'll try to setup a test system and see if I can reproduce it sometime, but don't have time right now.
