Fixing the randomly stopping WsusPool IIS Application pool and Windows Updates failed 0x80244022 error

I was recently assisting a client with an upgrade of their Configuration Manager (SCCM) environment up to the latest release of 1702 and as part of that we’re also going over it’s currently deployed functionality and making sure it all works. They recently noted that clients were no longer receiving updates and ran the Software Update functionality of ConfigMgr, which funnily enough also relies on WSUS to sync up to Microsoft (but not push out the updates themselves).

So when troubleshooting Updating issues, you need to check both the Software Update Point and WSUS, and lowe and behold the WSUS console kept on crashing. After checking the Update Services service, I then turned to IIS and noticed the UpdatedServices Application pool had stopped, so I started it and went back into the console but soon noticed it had died again. After reading some advice on the TechNet forums they suggested raising the memory limit of the Wsus Application Pool, which is done by selecting the Application Pool Name and then clicking Advanced on the right hand side or right click menu. Scroll down to the bottom of the Advanced Settings Window until you see Private Memory Limit (KB) and increase this from the default of 1843200 (which is 1.8 GB) to 4194304 (which is 4 GB). Make sure you have enough RAM allocated to the machine, if you are feeling courageous you can also set the value to 0 which does not set a limit.

After increasing the available memory to the AppPool, WSUS synchronized successfully and clients were now receiving updates

  1. Just wanted to say thanks! I just received a few complaints about this issue and your suggestions fixed this for me.

    1. Hi Bikash, could possibly be something else causing it to crash, do you see anything in the event viewer. If you have an extremely large number of clients all attempting to hit WSUS at the same time, you may need to increase the memory further.

  2. Setting it to 4GB did not fix it for me.
    Needed to increase it to 8GB. I think because the service was stopped for days now all clients are hammering wsus at the same time…
