I noted eventually at production server with almost 200.000 handle and wmiprvse.exe process with high cpu usage.
The server has approximately 200 processes running on Windows server 2012-R2 (virtualized with VMWare) with 12 processors and 12.4 Gb memory.
I discovered this article:
High CPU usage by WMIPRVSE.EXE process at regular intervals in Windows:
https://support.microsoft.com/en-us/help/4483874/high-cpu-usage-by-wmiprvse-exe-process
It is quoted that 50000 handle would be a value indicating that there is some problem.
This limit of 50000 must be respected?
