Server 2012 R2 DC Monitoring Host Private Bytes Threshold

Hi all,

I have been struggeling this one for some days now. Hopefully someone on the forums here can help me out with this one.

At a client site i have three 2012 R2 Dc's running. These servers have some agent memory problems. This show because the monitor "Monitoring Host Private Bytes Thresholds" turn to critical very often. When this monitor becomes unhealthy the agent is restarted.

The one i hoped would help in this environment was the WMI leak on DC's as decribed by Kevin Holman:

Unfortunately these hotfixes did not help.

These servers are comletely up-to-date.

Any suggestions?
