We are having repeated failures of our Application running on Jbos 4.05, mysql 5.083. Server works great for about 6 hours using no more then 10 connections to the mysql. Then suddenly get errors like:b. Looks like server attempts to open more connections, mysql connection peak at about 150 and then the server just hangs and looks like all DB operations fail with exceptions like mysql exceptions'Last packet sent to the server was 4 ms ago.'
