Hi, in case you have trouble with reproducing the problem, there is java option -XX:-HeapDumpOnOutOfMemoryError. Uli can run splitter with this option and then send you produced hprof file which you can open in MemoryAnalyzer or jhat. There you will see all allocated objects, what takes most memory and in case of memory leaks what keeps objects in memory.
