If you are getting a heap dump while using that setting then you ran out of heap memory. What are your JVM options set to? The best place to look for this is in the first few lines on the console after starting the app server. You are not, by any chance, running as a Windows service???

Could also attached the Heap Dump. There are other Java memory areas that will cause a OutOfMemory.
