* PROBLEM DESCRIPTION: The Websphere Application Server V4.0.1 *
*                      for z/OS and OS/390 takes too long to   *
*                      handle java.lang.OutOfMemoryExceptions. *

****************************************************************
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
