java.lang.outofmemoryerror suggests run out of memory in application server. quick workaround can increase max heap size in application server, in general should enable verbose gc , generate heap dumps. analyze dump looking memory leaks , learning taking space in heap.

you can use tools ibm support assistant (available free) :

• garbage collection , memory visualizer
• ibm heapanalyzer
