How many threads do you see in the taskmanager? Is that anywhere near the mentioned limit? > As a secondary question, is there any negative impact to shutting down > the 'jrun admin' instance?

(If you want to keep them running, put them back on their default memory configuration so they use considerable less memory.) That should give your server a lot of free memory to play with. I have had good results with setting -Xmx1280m and -Xmx1024m. This will make the instance grab 1024 MB at startup, but gives it room to increase to 1280 MB when needed. That way you can still see memory pressure by an increase in memory allocation, while you still get the big chunk at startup.
