Hello,
It seems like we have a memory leak in the termsvcs process of our RDS farm which occasionally occurs on a random machine in our farm. We have 10 session hosts on Windows Server 2012 R2 with current patch level who all serve around 20 to 30 users.
In this screenshot you can see the CPU and RAM load. Notice the steady drop in memory within the last 24 hours http://i.imgur.com/dz11fPz.png
Here you can see the process in question with a very high value in Private Bytes:http://i.imgur.com/Rh9SfzI.png - and in comparison the same process on a healthy session host with the same configuration and roughly the same amount of users connected:http://i.imgur.com/FCMVclD.png
Notice the difference the Private Bytes.
Does anyone else experience something similar? It seemingly started a week ago. So maybe related to a patch day.
