Hi Pete I have the exceptions caught for the scheduler, processor methods as well as the place where I invoke the saveAndSchedule() method. Don't see any other exception raised. The exception seems to happen after certain time period(I see all the relevant operations completed on the schedule object by that time like closing the JDBC connection, invalidating the objects etc.) after which the exception pasted by me is thrown at the end. I am not sure if I saw the right source here, org/jboss/ejb/txtimer/TimerImpl.java code seem to throw this exception on some timeout, not sure what could cause this timeout in my case. -- Mani.
