RHDS8 masters fail with no ingoing or outbound traffic

Solution Verified - Updated -

Issue

DS instances on both our masters of production environment had a big failure. We noticed high load on the systems. In error logs and access logs on the server we could see that no requests entered the directory server, only loadbalancer connections were OK.
