winmgmt.exe slowly uses more and more virtual memory - hotfix981314 did not help



Hello folks,

I'm hoping someone can help me solve an issue we are seeing on the server we have running PRTG. We are using a Windows 2008 R2 server, and are seeing an increasing amount of memory usage coming from winmgmt.exe. At the current moment, it is utilizing near 500mb.

I have researched this issue and found two hotfixes (KB981314 and KB977357), however, we have applied both hotfixes and neither have fixed the issue.

Any ideas?

Thank you! -Tom

Other than those hotfixes and doing some googling, we really cannot say any more than what you have already found. WMI is such a complex beast that you may have to contact Microsoft as I stated in the other KB article. Have you tried to move your monitoring to another server and stopping PRTG to see if that's the cause?

Does the other server then experience the same issue?
