APAR status

Closed as program error.

Error description

The client program starts threads throughout its longevity run.
A native thread-level allocation for 4096 bytes is not freed
when a thread terminates.   The client eventually ran out of
native storage.  This caused multiple
java/lang/OutOfMemoryError exceptions.  Also, observed was:

The client program starts threads throughout its longevity run.
A native thread-level allocation for 4096 bytes is not freed
when a thread terminates.   The client eventually ran out of
native storage.

Problem conclusion

Code has been modified in the "boss_thread_destructor" to free
the allocated 4096 byte area when the thread is terminating.

The storage is anchored by the "btcb_plx_dyn_area_ptr" field
(bbo3tcb.h).

APAR PM25162 is currently targeted for inclusion in Service
Level (Fix Pack) 7.0.0.15 of WebSphere Application Server V7.0.
