NumConnUsed 32 Count
WaitQueueLength 2 Count
Above two indicates that all 32 connections are given out by the pool and there are 2 requests waiting to acquire the pool. These requests will wait for a specified period (default : 60 seconds, wait-timeout-in-seconds attribute of connection pool) and then will throw "max-wait time expired" exceptions.
Can you post the connection pool configuration from domain.xml ? Is 'connection-leak-tracing' turned ON ?
