Hi, Haven't read the whole thread through yet, but to me it sounds like a garbage collection issue.
It can be, that the config application is using almost all the heap space provided by the JVM when idle, and when a change is done to the settings, the JVM has to do constant garbage collection in order to be able to instantiate new classes. The high CPU load can come from calling destructors continously. The JVM has a default limit on the max heap size(http://java.sun.com/javase/6/docs/technotes/guides/vm/gc-ergonomics .html) above which it will not grow even though the real machine has more free memory left. The default in your 2GB case -according to the link above- should be ~.5G. This can be increased by adding for eg "-Xmx1024m" or "-Xmx768m" to the JVM startup parameters in the startup scripts to test this theory. BR, Chris -----Original Message----- From: D. R.

Lang Subject: [sipx-users] Java goes to 89 percent an web console gets slow To further elaborate: My configuration is HyperV 2gig of ram 2 processors set for 30% allocated on quad core Intel. Whatever is triggering it is during changes to settings. It never starts until a change is pushed. My setup is also 12 station lines 1 PSTN, 2 ITSP trunks, a cisco 1760V bringing in the PSTN , FXS, and CISCO 7960. After restart the system is stable unless I make changes again. I typically leave the Web console up until it times out. In my case the phones are still working during the JAVA spike but as said even if I wait and it comes down the JAVA CPU utilization is higher than normal when you move between screens and does not go to normal until the restart. I will try the console method of restarting the process now that I have the syntax. I am in the process of getting Pigin and XMPP working.
