I upgraded from 1.1 to 1.2 a couple months ago and now we are seeing this:
Aug 20 05:34:38 kelly dovecot: auth(default): auth workers: Auth request
was queued for 7 seconds, 10 left in queue
...
Aug 20 05:34:38 kelly dovecot: auth(default): BUG: Worker sent reply
with id 53, expected 54
Aug 20 05:34:38 kelly dovecot: auth(default):
worker-server([email protected],dd.dd.dd.dd): Aborted: Worker is buggy
Aug 20 05:34:38 kelly dovecot: auth(default):
passdb([email protected],dd.dd.dd.dd): Fallbacking to expired data from cache
When I attempt to restart dovecot there is one dovecot-auth process that
won't die and keeps the server from starting. A simple 'killall
dovecot-auth' takes care of it and the server is able to start. I'm not
using anything exotic, dovecot config below.
The most curious fact is that we have identical servers running the same
version of dovecot (1.2.3, happened under 1.2.1 as well) talking to the
same MySQL database and both develop the problem at the same time. The
database is under considerable stress at the time this occurs as the
policyd tables are being cleaned. But this happens twice per hour and
only sometimes does dovecot have trouble. I'm working to move the
policyd database elsewhere, but of course this shouldn't happen in any case.
Any help would be much appreciated. Thanks!
