Sean, I like the theory, but there is one part that doesn't make sense. This error continued to happen until i restarted the service and more explicitily killed jrun. There are about twenty of the errors listed below. While it was happening i looked at Task Manager and zeroed in on the jrun process and it was running well under the 512MB limit. Which seems to point to the fact that it was no longer taking up 512MB of memory. If that is true then what was happening. Did it reach the threshold once and now not know how to recover from it even though the memory usage was much lower?

I suspect that at 12:28 there was sufficient activity on your system to require more than 512Mb RAM. By the time you checked later, that memory usage had shrunk back to 360Mb. This is not unusual. Since your machine has virtual memory, you can safely push the JVM max up quite a bit and heavy load will then just slow the system down rather than run it up against the memory limit. I think the maximum allowable is around 3600Mb (it's a certain amount under 4Gb but I can't quite remember what the threshold is). In order to scale your system, you could look at CFMX for J2EE which allows multiple instances and therefore multiple JVMs to service traffic on your website.
