Wow, that sucks. 1st step -- add validation queries to your connection pool configuration, if your pool supports them (most do). That will help the pool recover itself. 2nd step -- create a test environment where you can reproduce these problems. 3rd step -- reproduce the issue while running Tomcat in the test environment, and send a SIGQUIT (CTRL+BREAK on Windoze) to the JVM process to see exactly what threads are hung and where. That'll get you going in the right direction ;) Yoav This e-mail, including any attachments, is a confidential business communication, and may contain information that is confidential, proprietary and/or privileged.
