F5 Health Monitor getting 404 for /oam/server/HeartBeat

Customer is having 4 managed server and HeartBeat URL is working just fine. After customer added 4 more managed severs and the new server are failing and getting the following error 
We have many instances of "GET /oam/server/HeartBeat HTTP/1.0" 404 in our OAM server logs on only a couple of our servers. This is causing health monitors to fail. Why is this failing so much for about half of our servers and not for the other half? Here is an example from log file that shows how it will return 200 one time for a host, and then the next time a 404.
