Today our MOM 2000 stopped working. Looking on MOM Esrver local eventlog we found that every few minutes OnePoint starts , than we have message "BounceService: Service start of OnePoint failed. Error: 10" and it stops.
Attempt to start OnePoint manually didn't succeeded.
I was able to find workaround based on info from article http://www.huntland.co.uk/Downloads/MOM/ServiceBounceAsync.html
To start OnePoint service I had to disable rule for "Agents Consolidators or Data Access Servers"
(full path is Microsoft Operations Manager/Rules/Processing Rules Groups/Microsoft Operations Manager/Agents Consolidators or Data Access Servers/Performance Processing Rules/OnePoint service handle count > 10,000 (handle leak) - Bounce Service)
and rule for "Consolidator"
(full path is Microsoft Operations Manager/Rules/Processing Rules Groups/Microsoft Operations Manager/Consolidator/
Threshold Process-Private Bytes-OnePointService Consolidator - Bounce Service)
We will need to enabled them later and see what happened.
