Hello,
I too am running into this same problem. I have never had issues with MySQL
connections, and usually operate with 550 connections MAX (in my.sql). I
upgraded to 5.3, and I started getting a ton of "out of connection" messages. I
bumped to 1,000 connections just to try and make it through the day, and we are
exceeding that as well! This is a heavily used mailserver (if that wasn't
obvious from the numbers), but it has been rock solid for over 2 years. I'm not
sure where to go - but hoping progress is being made on this issue.
