IM & Presence 10.5 high CPU utilization



We have IM & Presence version Since it is 10.5, it is deployed as a CUCM subscriber node. After we finished configuration we added five jabber clients so that customer can test them. We are now experiencing high cpu utilization, values go from 85% to 90%.

We tried to reboot the node several times, but after some time the issue recurs. 

Critical processes, that consume most of CPU, are:

  • pe (Presence Engine) - 55&
  • ttsoft (Cisco Presence Datastore) - 27%

I haven't find anything in the log files that can be linked with high cpu utilization events.

Does anybody have similar problem or an idea how to resolve this issue?
