Rick, I understand that 5.4.5 fixed some things in mysql code but with the system that is currently in place, why would it work for months then all of a sudden out of the blue just stop working ???
Increased volume maybe ? I believe the symptoms you described occurred when MySQL gets overloaded and new connections are not allowed. If you are getting more and more volume, along with increased pop or imap access, then your MySQL server would start getting overloaded and the problem you reported would just "start happening" out of the blue.
