So I've been having much trauma with zfs and i386; but it seems it's
been narrowed down to the 'weekend'.
We leave friday and come back monday, and monday this box is not working
properly. Nothing has crashed, it's just slow.. but there is no load on
the box; just deathly slow.. 2+ minutes to log in at console for example.
A reboot fixes it and it's good for another week..
I think I have narrowed it down to the weekly locate job.
So tonight I'll run it by hand and see if the box dogs again.. but
assuming that is it..
what can I do about *that*?

/exports/squid is where the squid cache is, (aufs fwiw), and /home has
over 3k user accounts for samba.
wc -l /etc/passwd

the kernel is a simple one:
# I commented out i486 and i586 in GENERIC
# and debugging
cpu I686_CPU
ident GENERICplus
include GENERIC
options DEVICE_POLLING
options HZ=1000
options KVA_PAGES=512

options ALTQ_PRIQ # Priority Queuing (PRIQ)
options ALTQ_NOPCC # Required for SMP build
I have a simple pf.conf with some scrub and altq settings if anyone
thinks it might help.
but like I said I'm pretty sure it's locate now..
clues or questions appreciated.
