2 stange services slowing down my Jira 5.1

Dear all,

Whenever

com.atlassian.streams.internal.ActivityProviderConnectionMonitorImpl:activityProviderMonitor

com.atlassian.sal.jira.scheduling.JiraPluginSchedulerService

Or

com.atlassian.jira.plugin.ext.bamboo.service.PlanStatusUpdateServiceImpl:job
com.atlassian.sal.jira.scheduling.JiraPluginSchedulerService

but mainly the first one slows down a lot my Jira
I experience a very high CPU usage on one of my CPUs nearly locking my Jira instance.

Do you know those services (as the documentation says nothing more or less baout them) ?
I have disabled them by putting in delay 1000000000000
My Configuration :

Jira v5.1 under SUSE Linux with mySQL running on the same server
JVM memory options : JAVA_OPTS="${JAVA_OPTS} -Xms2G -Xmx2G"
Lastest Java Java(TM) SE Runtime Environment (build 1.6.0_38-b05)
Tomcat
Around 500 registered users
~ half of them currently logged

The Problem was in WMWare !

  • WMWare was not giving to Linux the RAM asked
  • Under linux the total RAM was reported there
  • But a non seen process was locking it
  • Instead of using real physical RAM Linux was swapping !
    It didn't know it
    So we add VERY high CPU usage and no reported Swap
