APAR status
Closed as program error.
Error description
In WebSphere Application Server V5.1.1.x, OutOfMemory errors
may occur in scenarios where a large number of WSIF requests
are submitted to the web services engine. This may occur if
the business process choreographer component of WBI Server
Foundation V5.1 is used to submit web services requests. When
the heap dumps are analyzed using the HeapAnalyzer tool, it can
be seen that a heap leak occurs here:

The problem is caused by the web services engine
ClientEngineFactory creating a hashmap that grows too large.
