Java.exe not decreasing 10.2 m030 cps09

Last week I updated my test server from 10.2 m020 csp08 to 10.2 m030 cps09.  After starting Windchill, the java.exe processes are staying constant in Memory size.  They are not releasing memory like they had been.  Is this something new or something broken?

How are you testing this?  Heavily loading the server, watching the RAM balloon, then seeing if it drops back down???

First I compared it to the numbers before upgrade and the production server which is still on m020.  In m020 the java processes would hang out at ~500,000-600,000 K.  I can see the memory increase when someone does something and then watch it drop a little after it goes idle.  In m030 the java processes increase to ~1,500,000 K when they are started and they just stay there.  There is no load on the system.  If I do a simple search, I see the CPU and memory increase on a java process but it just stays where ever it stops.

I'm refreshing my test server as I write this.  I will do a little testing with CPS08 and then reapply CPS09.  I'll let you know what I find.

You can check the value of maxHeap and minHeap in wt.properties

Update.  Over the New Year break I upgraded my production server and it is not having the same issues.  The only thing different was that I did not run Microsoft updates on the production server.
