Environment

Cause

This issue occurred because worker process requested application pool recycling due to private memory shortage. This happens when there is a Private Memory Limit set for vRA Application pools in IIS.

Resolution

To resolve the issue, set the application pool private and virtual memory limits to unlimited.

 

To set the application pool private and virtual memory limits to unlimited:

 

1. Log in to IIS Web Server.
2. Open the IIS Manager and navigate to Main server (below Start Page) > Application Pools
   
   Note: The Main Server name vary depending on your environment
    
3. Select the RepositoryAppPool and click on Advanced Settings.
4. On the Advanced Settings page:
    
   1. Change Load User Profile setting from False to True.
   2. Change the Private Memory Limit to 0 (which means unlimited)
   3. Change the Virtual Memory Limit to 0 (which means unlimited)
       
5. Select the other pools, vCACAppPool and WapiAppPool and repeat the actions of Step4.
6. Restart the application pools.
    

Note: The first access will be slower, but the subsequent access will be fine.
