Symptoms

With a very large heap (e.g. 2Gig or more) and on a server with many processors (e.g. 32), major or full GarbageCollection (GC) can take a very long time and cause message flow to temporarily halt. Switching to "Concurrent Mark Sweep Garbage Collector" (low pause) might help, but can cause the whole JVM to hang during a major GC.
