Hello,

I have Jenkins in version 2.190.3 and it is on an Amazon Linux EC2 on AWS.

The application and nginx are in docker containers.

My nodes are in a Kubernetes cluster.

The connection between the Master and the Nodes are via Peering connection (fully AWS network).

I often experience the following problems:

16:10:46 infra-tekton-qnr5s was marked offline: Connection was broken: java.nio.channels.ClosedChannelException 16:10:46 at org.jenkinsci.remoting.protocol.NetworkLayer.onRecvClosed(NetworkLayer.java:154) 16:10:46 at org.jenkinsci.remoting.protocol.impl.NIONetworkLayer.ready(NIONetworkLayer.java:142) 16:10:46 at org.jenkinsci.remoting.protocol.IOHub$OnReady.run(IOHub.java:795) 16:10:46 at jenkins.util.ContextResettingExecutorService$1.run(ContextResettingExecutorService.java:28) 16:10:46 at jenkins.security.ImpersonatingExecutorService$1.run(ImpersonatingExecutorService.java:59) 16:10:46 at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) 16:10:46 at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) 16:10:46 at java.base/java.lang.Thread.run(Thread.java:834)

Can anyone help me please?

It's impacting the production environment.

Thank you!
