A fix is available
WebSphere Application Server Version 4.0 Fix Pack 3 (Version 4.0.3)

APAR

APAR status
Closed as program error.

Error description
PQ54061 was provided to correct a problem with dynacache.
The readme file of this eFix simply states to update the
classpath and also to put the pq54061.jar file on the system.
A problem with this is that if /usr/IBMWebAS/dynacache.xml
does not exist ( which it does NOT on wasv353 )---- Then when
the application attempts to use the new feature it causes the
jvm to crash.

Problem summary
****************************************************************
* USERS AFFECTED: WebSphere Application Server users of        *
*                 dynamic caching                              *
****************************************************************
* PROBLEM DESCRIPTION: If dynamic caching is utilized when a   *
*                      dynacache.xml file is not present,      *
*                      then a core dump may occur.             *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
When the DynaCache component was initialized without a
dynacache.xml present, InitializerErrors were thrown which
resulted in a JVM core dump.
Problem conclusion
This problem was caused by a prior dynacache fix, and this is a
cumulative APAR to correct the problem of not properly handling
proxied servlet output streams and the java core when there is
no dynacache.xml file.
Temporary fix
