Timeout caused by wait for mutex (PE035) only on Windows Server 2008 R2

Modified on 2025-06-10 22:53:53 +0200

Hello, I use the Windows Update Status Sensor for my virtuel Windows Server 2008 R2 / 2012 R2. The sensors worked fine on both. Since few weeks the sensors on all Windows Server 2008 R2 throw the PE035 error: Timeout caused by wait for mutex. Tested: Run the LastWindowsUpdateSensor.exe for a Windows Server 2008 R2 in a CommandLine. The executions are successful, but run between 15 and 30 minutes and the svchost.exe get up to 100% CPU. In comparison to 2012 R2 the execution run only 30 seconds. Does anybody has an idea?

Thanks.

Hello,

The mutex handling of the Windows Update Sensor will be improved in future versions of PRTG. This new version is integrated in the latest preview version of PRTG at the moment, so it should be available within the stable version 15.x.19.x
