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(xxx at example.com,dd.dd.dd.dd): Aborted: Worker is buggy Aug 20 05:34:38 kelly dovecot: auth(default): passdb(xxx at example.com,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!

It may be a long time until it happens again since I've moved the slow databases, but I'll try to break the old version and the patched version and post the results. Thanks, David
