Regarding the stack spaces I noticed it was pretty high for workspace and we were seeing weird issues with logins -- after making the stack space on Weblogic Workspace more like defaults (128k) it seemed to clear things right up. So I'm not sure that changing stack size is a good idea in general -- the heap size (mx) is definitely something to change like you found out.
