    Unknown Internal JBoss/Tomcat Errors

    Austin Kotlus Newbie

      I am running JBoss 3.2.2 RC4 with Tomcat under JDK 1.4.2.
      JBoss is configured to use MySQL as it's Default Datasource (DefaultDS), Auto Increment of Primary Keys, and JAAS Database Authentication.

      My Application is working flawlessly but JBoss is throwing a NullPointerException (even when my EARs are not running) every 45 - 90 minutes. As the stack trace shows, the error does not touch any deployed code.

      Does anyone know what causes this?
      Here is the Stack Trace:
