Just a very brief "me too" (but possibly different effect): I'm stress testing two machines I put together over the weekend with an endless loop of make -j4 universe, with /usr/obj on ZFS, with a single disk. One of the two machines has now been stuck for a couple of hours, and trying to access /tank results in a hung process, as will zfs list. I'll reboot and see what happens, and if I can trigger it again, willt try to produce more details. I have set vfs.zfs.arc_max="512M" vfs.zfs.prefetch_disable=1 in loader.conf FreeBSD lokschuppen.lassitu.de 8.0-CURRENT FreeBSD 8.0-CURRENT #1: Wed Dec 3 07:05:03 UTC 2008 root@lokschuppen.lassitu.de:/usr/obj/usr/ src/sys/EISENBOOT amd64 Stefan -- Stefan Bethke <stb@lassitu.de> Fon +49 170 346 0140
