Unable to add a new host connection to the hypervisor with error: XDDS:157EE393.Looked up the detailed error message. Found: Exception of Type: 'System.OutOfMemoryException' was thrown

- Verify if there is a memory leak on the hypervisor or on the controllers
- Reboot all the Delivery Controllers in that site
- If it does not help with the issue reboot the Hypervisor as well
- Check for any processes causing memory leak on the Hypervisor or on the controllers.

Problem Cause

The allocated memory for the processes is not released in a timely manner. Hence the SSL validation fails because of insufficient memory.
