      Additional heap dumps can be provided, but all show pretty much the same.

      The broker is configured with the attached rximage-activemq.xml. It appears that the StoreQueueCursor is exceeding its memory limit and eventually results in an OOME.

      This is being encountered with an IBM 1.6 JVM, which has been given a max heap size of 2G. Fuse 6.1 R4 is being used.

      The attached heap dump was analyzed with IBM's HeapAnalyzer tool. A screenshot of the offending Queue has also been attached. It appears the average message size is ~20MB.

      This is very similar to ENTMQ-1180 and may indeed be the same problem.
