Problem: SCCM 2012 WSUS fails with error message "System.Net.WebException: The request failed with HTTP status 503: Service Unavailable"
After more investigation it appears in IIS the Application Pool "WsusPool" would enter a stopped state and WSUS would fail synchronization.
Solution: After some reading it seems this is memory related. Increasing the memory allocation in the Application Pool/Advanced Settings didn't seem to resolve the issue.
Instead I disabled the memory limitation altogether in the IIS recycling settings for the WsusPool Application Pool. I'm also using Hyper-V and the Dynamic Memory feature. I boosted the minimum ram for the SCCM virtual machine to 4GB which should be enough. I believe Hyper-V was starving the virtual machine for ram and thus causing the WsusPool to stop.
