Today, Microsoft released Update Rollup 1 for the System Center 2012 SP1 suite. Since this is an Operations Manager blog, I´m only listing whats new for SCOM. So what´s been fixed since the 2012 SP1 release?
Agentless Exception Monitoring (AEM) in Operations Manager may provoke an increase in reporting threads and choke points.
After the Alert Attachment Management Pack (Microsoft.SystemCenter.AlertAttachment.mpb) is imported, you create a dashboard that contains an alert widget. When you click an alert, the Operations Manager console may crash.
When a Windows PowerShell module uses the Monitoringhost.exe process on an x86-based client that is running Windows 8, more than 800 megabytes (MB) of memory may be consumed.
After an application domain is created, adding another application domain may be unsuccessful.
The update can be downloaded either via Windows Update or manually via http://catalog.update.microsoft.com/v7/site/Search.aspx?q=2784734 (Requires IE 6.0 and later to work properly)
