    Description

      Symptom

      If you run a job via the cli with the "-s" switch and the job does not print any output for longer then 5 seconds, the connection dies with "java.io.IOException: Unexpected termination of the channel"

      Note: hudson.diyChunking is needed for https://issues.jenkins-ci.org/browse/JENKINS-35197

      /usr/bin/java -Dhudson.diyChunking=false -jar /usr/lib/jenkins/jenkins-cli.jar -s http://127.0.0.1:8080 -i /root/kenkins_ssh_key build -s JOB

      Problem

      The Jenkins built in Winstone-Jetty server uses a keep alive of 11,25 seconds (see https://github.com/jenkinsci/jenkins/blob/master/cli/src/main/java/hudson/cli/CLI.java#L156), while the jetty is configured with a 5 second timeout (see here https://github.com/jenkinsci/winstone/blob/master/README.md#command-line-options).

      Workaround
      Specify --httpKeepAliveTimeout=15000 to start of Jenkins

            The diagnosis looks reasonable to me. Keep Alive timeouts need to be aligned by default

            Please provide the full stacktrace. The provided snippet is not enough to diagnose the cause. Are you also sure that CLI client version is aligned with Jenkins version?

            I have this problem too. I'm using the latest Jenkins 2 Docker image. I can't figure out how to set the keep alive timeout.
