WSUS Crashing - WSUSPOOL Stopping in IIS

Problem

 WSUS MMC Crashes and WSUS Generally unreliable.

Cause

 Application Pool "WSUSPool" Stopped in IIS

Solution

To improve WSUS availability, you need to increase IIS Private Memory Limit. The default limit is set to 1843200KB. And when an IIS worker process uses more than 2GB WSUS crashes and the problem occurs.

Change Private Memory Limit (KB) to a higher number that fits your server specifications or simply 0 , which means no limit, instead of the hard-coded 1843200. Follow this path to find the setting:

 

WSUS Application Pool IIS Advanced Settings

Internet Information Services (IIS) Manager → Server → Application Pools → Select “WSUSPool” → Actions Advanced → Recycling → change “Private Memory Limit (KB)“.

This’ll improve WSUS availability.
