Subject RE: Understanding Messages in the Debug.log

Thanks Jacob,

I’ve already seen this, but it doesn’t answer my question, as this is a production Cluster,
which at present, has no data and is not being written too, its being built to go live shortly,
so with no data, a Keyspace with a table designed but no data in it, only system databases,
what on earth could be causing load on the cluster to cause the error message??

Good Morning Community,

Can anyone help me understand what these messages (and I have a lot of them in the log) mean,
they must be a symptom of something but I am unsure how to starting working this out.

I’m using C* 3.0.11, CQL 5.0.1.

I have 6 node ring over 2 DC’s (3 in each DC) each of the nodes has this message in the
log.

The message in the debug log is
DEBUG [GossipStage:1] 2017-09-21 09:19:52,627 FailureDetector.java:456 - Ignoring interval
time of 2000275419


There are so many of these messages, I’d like to find the root cause of this, if anyone
could help that would be great. Or if they can be ignored, how do I supress these?

Thanks
J
