We are running PRTG version 16.3.4470+ since the 20th of June. We have multiple servers (all W2K12 R2) with event 5612 in the Application Log.
Windows Management Instrumentation has stopped WMIPRVSE.EXE because a quota reached a warning value. Quota: HandleCount Value: 4101 Maximum value: 4096 WMIPRVSE PID: 2224 Providers hosted in this process: %windir%\system32\wbem\servercompprov.dll, %systemroot%\system32\wbem\cimwin32.dll, %SystemRoot%\system32\wbem\policman.dll
On multiple servers the servers have started to become unresponsive to RDP - logon via Idrac / VMWare console - we cannot stop/start services anymore. The only way so far is to power off the server completetly. (The server itself is running but unmanagable )
Event 5612 point to an overload/memory leak of WMI but we are checking our servers only for the status of some services and diskspace free space. (in addtion to Ping / RDP). So we have +/- 5 sensors per server.
We are running only one other product for inventory that uses WMI which is Lansweeper but that has not been upgraded recently.
I am not saying that PRTG is the root cause but we have never had 5612 events before June. They started to occur a week - two weeks after PRTG upgrade.
We just want to find a solution so these issues don't occur and we have to force the shutdown of an important server.
Not sure what I can do to find out the root cause.
