Windows 2012 Core Extreme memory use on SVCHOST/Workstation service

Solution 1:

I had an eerily similar issue where the svchost was destroying the server performance.

The solution: Turns out I had a full Event Log. I cleared it out and everything was back up and running like nothing ever happened.

(I also recommend changing the size of the event log from the default, see below)

To set maximum log size by using the Windows interface
- Start Event Viewer.
- In the console tree, navigate to and select the event log you want to manage.
- On the Action menu, click Properties .
- In Maximum log size (KB) , use the spinner control to set the value you want and click OK .

It sounds exactly like what is happening here, but ended up being a really easy fix. A restart would temporarily solve the issue, but as soon as anything tried writing to the log, everything would spiral out of hand and just kept eating up resources.

Hope this helps!
