We've been seeing a lot of mupdate worker thread problems the last 2
days.
Things like
Jan 24 12:38:42 notdog mupdate[5295]: could not start a new worker
thread (not fatal)
Jan 24 12:38:42 notdog last message repeated 353 times
Jan 24 12:38:45 notdog mupdate[5295]: login:
mettwurst.cc.columbia.edu [128.59.33.138] backend PLAIN User logged in
we're trying to debug the cause of the problem, but I'd thought I'd
ask on the list if anyone had any insights.
Logins are infrequent and generally there aren't that many
connections established.
> lsof | grep "mupdate->" | wc -l
18
We increased the max number of worker threads, and max connections
mupdate_workers_max: 400
mupdate_connections_max: 1792
We increased a lot of the ulimits
and increase the maxfds
mupdate cmd="mupdate -m" listen="mupdate" prefork=1
maxfds=5048
We're running on RHEL4 and Cyrus 2.3
Thanks for any help or pointers.
