One other thing of note. I just now looked at the record I captured of the last hang. I looked for other processes waiting on puffsrpl, on the theory that if there are two unexpected such, there may be others.
There are: 557 1 3 0 84 d2251500 mailwrapper puffsrpl 3985 1 3 1 84 d1c3ba80 bozohttpd puffsrpl 19816 1 3 0 84 d23d9360 smtpd puffsrpl 557 1 3 0 84 d2251500 mailwrapper puffsrpl 3985 1 3 1 84 d1c3ba80 bozohttpd puffsrpl 23619 1 3 1 84 d68ef080 bozohttpd puffsrpl 3698 1 3 0 84 d2eafca0 as puffsrpl 23176 1 3 1 84 d1f3b7e0 git puffsrpl 7871 1 3 1 84 d1e382a0 bozohttpd puffsrpl bozohttpd, those do not surprise me. At least half the hits I get these days are fetching from the puffs mount (it's /export/ftp/pub/mouse/git-unpacked; /export/ftp is also the root directory used by bozohttpd.) The git and one of the mailwrappers were at the end of the tstile wait chains I found. That leaves the other mailwrapper, the smtpd, and the as. None of those five would I expect to be going anywhere near the puffs mount point. That an as is running does not surprise me; I had a build-of-the-world going when this happened. But it shouldn't've been touching anything outside of /usr/src, the build-into directories, and /tmp (or moral equivalent - /usr/tmp, or /var/tmp, or some such). I'm going to have to get stack traces next hang. I've now set up a dump partition, so I have a fighting chance of getting a kernel dump. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
