![]() APAR status Closed as program error. Error description When there is an uncaught exception in the customer's valueUnbou nd() method, invalidation thread is going to sleep. This causes slow invalidation of session objects, and shows symptom similar to a memory leak.Local fix Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server -- Session * * Manager Users * **************************************************************** * PROBLEM DESCRIPTION: Robust Handling by Invalidation * * Thread required for an exception * * thrown in the valueUnbound method. * **************************************************************** * RECOMMENDATION: * **************************************************************** The Invalidation Thread in the database persistence case during listener processing reads in the object from the database and invokes the valueUnbound method. If the valueUnbound method throws a RunTime Exception the Invalidation Thread was halting that particular round of invalidation processing and would resume processing only after the sleep interval.Problem conclusion This has been changed so that the session on which the Runtime exception is not invalidated and the Invalidation Thread continues with the invalidation processing for the other sessions.Temporary fix Comments
