[log] Sep 22, 2016 9:15:40 AM hudson.remoting.SynchronousCommandTransport$ReaderThread run [log] SEVERE: I/O error in channel Chunked connection to http://127.0.0.1:8080/cli [log] java.io.IOException: Unexpected termination of the channel [log] at hudson.remoting.SynchronousCommandTransport$ReaderThread.run(SynchronousCommandTransport.java:73) [log] Caused by: java.io.EOFException [log] at java.io.ObjectInputStream$PeekInputStream.readFully(ObjectInputStream.java:2353) [log] at java.io.ObjectInputStream$BlockDataInputStream.readShort(ObjectInputStream.java:2822) [log] at java.io.ObjectInputStream.readStreamH ... 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 Add Comment   This message was sent by Atlassian JIRA (v7.1.7#71011-sha1:2526d7c) -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
