He's seeing odd things happen on his machine that I'm not seeing on mine with the same vintage stable. These odd things look like something is dancing in kernel memory. Specifically, his routes for his SLIP interface gets messed up and the uptime reported by ps shows negative numbers. He reboots, the problems go away and life is good for 12-48 hours when they come back again. He also has about 5 people that dial into 2 modems and run elm, pine and lynx. Some of them as slow as 2400 baud which seems to tickle another kernel bug: If they are doing something like cat /etc/termcap and hangup in the middle, the tty port "hangs" and you can't get a couple of processes that are holding it to die. He's seen this since 1.1.5.1R. Does this sound like anything that people have seen in -stable (or even -current)? Any ideas what the problem might involve? We're looking at the whole system right now to make sure that all the parts in it are in spec and sane. What was the conclusion of the "anybody got a good memory tester?" thread. I don't think I saw one more specific than "Run FreeBSD. If it fails, then you have bad memory." Kernel data isn't swapped, right?
