PK98081: OUTOFMEMORYERROR COULD OCCUR DURING LONG RUNS IF WEB SERVICE APPLICATIONS ARE RUN UNDER HEAVY LOAD

Fixes are available

APAR status

Closed as program error.

Error description

If a large number of JAX-WS web service applications are
running for a long period of time, a java.lang.OutOfMemoryError
error could occur.

The JAX-WS applications locate the remote web services using
endpoint URLs.  If these URLs contain unique session
information then an OutOfMemoryError is more likely.

Note that it is rare for an endpoint URL to contain unique
session-based information, but it is possible.  The presence
of session-based information is dependent on how the endpoint
URL is used by the particular application.

If a large number of JAX-WS web service applications are
running for a long period of time, an OutOfMemoryError error
could occur.

The JAX-WS applications locate the remote web services using
endpoint URLs.  If these URLs contain unique session
information then an OutOfMemoryError is more likely.

Note that it is rare for an endpoint URL to contain unique
session-based information, but it is possible.  The presence
of session-based information is dependent on how the endpoint
URL is used by the particular application.

Problem conclusion

The JAX-WS engine stores each of the endpoint URLs in a cache.
The presence of the unique session-based information in the URL
causes the cache to grow in size.  Ultimately, the size of the
cache may cause an OutOfMemoryError condition.

The JAX-WS engine is corrected to remove the query string
(session-based information) prior to storing the URL in the
cache.  The removal of this unique information ensures that
the cache size remains small.

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.9.
