I would add -d64 to make that explicit. My comments on using Hotspot defaults for GC stand, unless you have good motivation otherwise. I note you trigger CMS very early, when 70% full rather than the default 92%... is there a reason for that?
If you are sending enormous messages, I suggest using JMS to send a pointer to the file system from which the messages can be retrieved. Finally, I would ask what version of java? Newer is *much better* in the area of GC. ----- Michael Hayes B.Sc. (NUI), M.Sc.
