Paulo Motta updated CASSANDRA-16313:
------------------------------------
Description:
When a node becomes down a periodic attempt is made to try to reconnect to the
node. However, the connection error
[spams|https://github.com/apache/cassandra/blob/cassandra-3.11/src/java/org/apache/cassandra/net/OutboundTcpConnection.java#L546]
the debug.log of all nodes in the cluster with the following message:
{noformat}
DEBUG [MessagingService-Outgoing-/XX.YY.ZZ.WW-Gossip] 2020-12-04 09:13:58,999
OutboundTcpConnection.java:546 - Unable to connect to /XX.YY.ZZ.WW

I've seen cases where this rolled the entire debug.log which can difficult
troubleshooting.
We should probably guard this in a NoSpamLogger.

I've seen cases where this rolled back the entire debug.log which can difficult
troubleshooting.
