Hi Kirby, Thanks for your reply! There's nothing else unusual about my setup.
For my test case, I'm passing nothing but the parameters I originally posted, so the memory configuration should be the default. IIRC, that's 128Mb in total for the heap. I have tried forcing a GC, but that doesn't seem to help - I still get thousands of those sleeping threads being created (especially as my test case does nothing but an infinite search loop!) and it appears that's what's eating up all the available memory. I've also seen this give me grief with Tomcat restarts - not sure if it's the same issue, but I frequently have to issue a kill -9 to stop the process. I also noticed that when I ran a simple search using my test case code (i.e. just one pass, not an infinite loop), it often took a while before I got back to the prompt, indicating that something was still spinning.... Thanks again, -Mark
