FIX: Slow performance when System Center Operations Manager monitors a computer in BizTalk Server

Symptoms

When you use Microsoft System Center Operations Manager to monitor a computer that is running Microsoft BizTalk Server 2009 and BizTalk Server 2010, BizTalk Server experiences slow performance.

Note When this issue occurs, you may experience the following issues:

• You cannot log on to the computer.

• You cannot start BizTalk Administration Console.

• A Service Host process (Svchost.exe) consumes a large amount of memory.

Cause

This issue occurs because of deadlocks that occur when BizTalk threads run BizTalk Windows Management Instrumentation (WMI) queries. Therefore, the Svchost.exe process that hosts the WMI service (Winmgmt) may eventually create thousands of threads.

Resolution

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

Workaround

To work around the issue, restart the server periodically.
