Hi guys, I have been investigating XX-7634 which reports high CPU utilization by java processes after an ISO install of the commercial version (SCS) which uses the IBM JVM.
Basically, after an ISO install I'm seeing that *all* the java-based processes chew up between 50% and 100% of one processor and remained like that for as long as I kept the box up (few hours). The processes in question are sipXpage, sipXivr, sipXrelay, sipXconfig, sipXrest and sipXprovision. Using jconsole I was able to find that the hot thread for each of these services is called 'Attach Handler' (com.ibm.tools.attach.javaSE.AttachHandler.run()) and I also found that I can eliminate the high CPU condition completely on a fresh install by hand-editing the launch command for each of these java processes to add the following property: -Dcom.ibm.tools.attach.enable=no If I add this property then all the processes are well-behaved but I do not understand the fundamental reason why the hot thread is there in the first place. I'm therefore turning to the Java gods that are tuned in to this list to see if they had previous encounters with this. Thanks in advance, bob _______________________________________________ sipx-dev mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-dev Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-dev sipXecs IP PBX -- http://www.sipfoundry.org/
