Subject Re: How to get a stack trace
Date Mon, 03 Aug 2009 01:20:01 GMT
Your heap may be just too small or you may have a memory leak.  A stack
trace may not help you since the thread encountered the OutOfMemoryError may
not be where the memory leak is.  A heap dump will tell you what's using up
all the memory in your heap.
