Then a major GC likely is running almost continuously, which will suspend the application threads. What are your heap-related commmand line settings? If you have artificially constrained the size of the OldGen, you could easily have a self-induced problem. Setting -XX:NewRatio or any of several other options will prevent HotSpot from dynamically adjusting the balance between NewGen and OldGen. Or, you may simply be out of heap space, in which case you'll need to fix your application so that it's not so greedy. Excessive caching without employing a SoftReference technique is a frequent cause. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
