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*?

bootloader.conf:

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

wc -l /etc/passwd
    3289 /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
options         ALTQ_CBQ        # Class Bases Queuing (CBQ)
options         ALTQ_RED        # Random Early Detection (RED)
options         ALTQ_RIO        # RED In/Out
options         ALTQ_HFSC       # Hierarchical Packet Scheduler (HFSC)
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.
