Subject Re: Understanding Messages in the Debug.log
Date Thu, 21 Sep 2017 11:44:37 GMT
The message is caused by the Gossip message exchanged. It doesn't have
anything to do with the load on the cluster. I asked the same question on
the datastax slack. This is the answer from one of the Datastax engineers
(Erick Ramirez):

"`FailureDetector` checks if a node hasn't responded for 5 seconds before
marking it as down, otherwise it doesn't do anything (ignores) if last
response was within 5 seconds (`2002779703` 2 secs in your case)
what i'm trying to say is that you don't have to worry about anything"
