Comment	> Any progress on this bug? We have a fairly large user base (approx > 75000 users, 10-1500 users actually login daily). We recently > upgraded from an older Horde version to the Horde Webmail Edition > 1.2.2. With the upgrade, we now have 3 load balanced webmail servers > all talking to one Mysql server (ver. 5.0..32, dual proc, dual core > 2.0 GHz Xeons with 4GB RAM). > > The webmail servers are holding up great, but the MySQL box is under > heavy load. We've done a fair amount of tuning and tweaking, but we > appear to be affected by this "bug". When we run "mytop" we > consistently see queries similar to the one mentioned in this bug > (for turba, nag, mnemo and kronolith tables) which do not use indexes > and create temporary tables. These are also the only queries that > show up in the mysql-slow.log. > >
