Matthew Mitchell commented on JENKINS-28492   Re: The server rejected the connection: *** is already connected to this master. Rejecting this connection. So I think what's going on is that certain kind of network outages (or maybe a reboot) are causing issues with the master realizing that the connection is closed. I think I see one place where there is a bug: https://github.com/jenkinsci/jenkins/blob/master/core/src/main/java/hudson/slaves/ChannelPinger.java#L111 I've seen the call into the PingFailureAnalyzer return NPE, causing us to miss the call to terminate the channel. However, unless I'm misunderstanding the code, I think that's executing on the client, which wouldn't cause the server to keep the channel open. Do you have any special ping setting set on Jenkins startup?
