I've been in the process of moving my pop3 proxy over to the dovecot proxy. I have a ton of users using pop3 still, and am seeing these errors popup within a minute or so of the connection to the database:

Password query failed: Not connected to database

Eventually the auth-worker will reconnect to the database and things will go on normal for another minute or two, then the same issue occurs. I'm runing MySQL 5.0.22 on FreeBSD 6.1. I upgraded to 5.0.27, however I started getting the: "Password query failed: Commands out of sync; you can't run this command now" error instead. So I downgraded until I could figure out this issue first.

I've tried connecting to localhost, /tmp/mysql.sock, and a remote server and all exhibit the same problem. The MySQL idle timeouts shouldnt come into play because I'm constantly having users check their accounts.

Any insights will be useful,

Thanks!

Cassidy
