Ok, next question...
Is anyone who is having these problems NOT using UFS2?
I've been slowly changing one major-ish thing at a time on the machine
I'm having problems on and then seeing if I could wedge processes afterwards.
Until now wedging them has been trivial, no more than 10 minutes' worth
of running find's. Since shifting all the disk partitions on the machine
from UFS2 to UFS1 two nights ago I haven't been able to wedge anything.
It even survived a full backup which it hasn't done for months now.
I'll keep testing for a while to make sure but at this point if a similar
change is easy for any of the other people reporting this problem it
might be worth giving it a try...
If I'm not successful wedging anything after a couple of days I'll try
moving one of the partitions back to UFS2 and see if I start having
problems again.
