Was a heap dump taken in order to find where the memory was being used? If not, reproducing the problem and grabbing a heap dump after the out-of-memory is reported (or using the create-heap-dump-on-oom JVM option) will make it feasible to track this down.
Based on the description of the problem, the OOM is not expected. -- View this message in context: http://activemq.2283324.n4.nabble.com/java-lang-OutOfMemoryError-Java-heap-space-tp4680177p4680186.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
