The System logs in the Event Viewer showed:

Warnings about ports 44441,44442,44443,4444 of the Policy Server

Closing a TCP socket with local port number 44442 in process 2636 is taking longer than expected. The local port number may not be available until the close operation is completed. This happens typically due to misbehaving network drivers. Ensure latest updates are installed for Windows and any third-party networking software including NIC drivers, firewalls, or other security products. 

Cause

It was determined that a batch of Microsoft Security patches had been applied to the server.
The customer then proceeded to test each patch individually to isolate the problem.
 

Environment

Policy Server 12.52 SP02 CR01
Windows Server 2012 R2

Resolution

It was specifically narrowed down to KB4338824 from July 10, 2018. Removing this Windows patch resolved the Policy Server crashes.
