![]() APAR status Closed as program error. Error description This apar was taken to address java.lang.OutoutMemoryExceptions more gracefully on Websphere Application Server on OS/390 and Z/OS.Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * version 4.0.1 for z/OS and OS/390. * **************************************************************** * PROBLEM DESCRIPTION: The Websphere Application Server V4.0.1 * * for z/OS and OS/390 takes too long to * * handle java.lang.OutOfMemoryExceptions. * **************************************************************** * RECOMMENDATION: * **************************************************************** When the JVM in a WebSphere Application Server region runs out of memory, Garbage Collection takes over for about 13 seconds before the server gets an OutOfMemory error (about 13 Garbage Collection cycles). Then another 77 seconds later, the server region finally takes a CEEDUMP. This means that 90 seconds elapsed from the time the initial OutOfMemory error occurred until the dump was attempted.Problem conclusion To fix this problem, the WebSphere Application Server V4.0.1 code was modified to exit the jvm with an exit code of -1, whenever OutOfMemoryError condition occurs. APAR PQ72866 is associated with SERVICE LEVEL W401606 of WebSphere Application Server version 4.0.1 for z/OS and OS/390.Temporary fix Comments
