This article describes the issue when you receive the following error prompt:

Download failed. Http status 503 - temporarily overloaded Error Code: 0x80244022



All versions of Patch Manager



The WSUS application pool's Private Memory Limit is not set high enough causing the http 503 temp overload.



  1. Open the IIS Manager on your WSUS server. 
  2. Highlight Application Pools and select your WSUS application pool from the list.
  3. Right-click and select Advanced Settings.
  4. Scroll down and increase the Private Memory Limit from the default 1843200kb (1.8GB) to 8000000 (8GB).
  5. Restart the application pool.
  6. Attempt the update management task again.
