I think I might have found *at least* one of the problems, and that being
the excessively high blocked states while ps isn't finding anything ...
MySQL
We just recently started allowing clients to run a MySQL server *within*
their vServer ... in a drastic move, I just shut them all down on pluto,
and blocked drop'd from ~86 down to 5 in a matter of moments ...
restarting them all has it climbing once more, being up around 22 already
...
I'm going to go with that theory for now, and keep an eye on things ...
Just curious as to why, even with -H, its not showing any blocked states
within ps though ... ?
Thx

Yes, this looks like a deadlock. As I understand, that's on 6.1-STABLE ?
Yes, kernel sources, it seems, from May 25th, according to my /usr/src

BTW, do you use snapshots ?
Not that I've explicitly enabled ...
I think that without ddb access, diagnose and debug the problem would be
quite hard.
Would it be a simple matter of:
CTL-ALT-ESC
panic
to get it to dump core? Or would more be involved? Would a core dump
even work?
Core dumps are somewhat unconvenient in this situation. Better,
sending report to me, follow my advise in
