I had a similar issue on -current a few weeks ago, with processes that would lock up and become unkillable when they tried to access certain parts of the filesystem (running all zfs here). One time it managed to lock up every time you'd do an ls /, but a reboot would always clear it, then a few days later it would pop up again somewhere else. I never lost any data, zfs never found anything wrong, and the drives and hw all checked out. I sync'd up with the latest -current on oct 18th and it stopped happening (or maybe I just stopped noticing it, entirely possible for a very lightly used personal box), plus I was traveling and super busy at the time, so I didn't bother pursuing it further. -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
