Notice: KB2775511 triggers Event 2115 in Operations Manager

The Operations Manager support team has identified a regression in a recent Windows update. After installing the following update on Operations Manager Management Servers, agents or servers may be affected by a deadlock.

KB2775511 - An enterprise hotfix rollup is available for Windows 7 SP1 and Windows Server (http://support.microsoft.com/kb/2775511)

Once in deadlock, Management Servers will generate HeartBeat failures and will go into a “greyed out” state. grayed out

As a result, devices managed by these Management Servers will also go into a “greyed out” or “not monitored state.”

When in this state:

1. No new events will be generated in the Operations Manager Event Log

2. Errors in State Change Events will appear frequently

3. Alerts will be generated during state change

Removal of KB2775511 will correct the issues introduced. The OpsMgr team recommends that Operations Manager users refrain from installing KB2775511 until this deadlock issue is resolved. New information will be posted as it becomes available.
