[JIRA] [ssh-slaves-plugin] (JENKINS-26884) Slave disconnect should be *nicer* during restart

Tue, 10 Feb 2015 09:33:39 -0800

Issue Type: Bug Bug
Assignee: Kohsuke Kawaguchi
Components: ssh-slaves-plugin
Created: 10/Feb/15 5:31 PM
Description:

While managing modules, I am offered a "restart" button, but when I click it, it logs this message:

Feb 10, 2015 10:00:46 AM jenkins.model.Jenkins$23 run
SEVERE: Restarting VM as requested by username
Feb 10, 2015 10:00:46 AM hudson.plugins.sshslaves.PluginImpl closeRegisteredConnections
INFO: Forcing connection to ft-dbadmin:22 closed.
Feb 10, 2015 10:00:46 AM hudson.remoting.SynchronousCommandTransport$ReaderThread run
SEVERE: I/O error in channel ft-dbadmin
java.io.IOException: Unexpected termination of the channel
	at hudson.remoting.SynchronousCommandTransport$ReaderThread.run(SynchronousCommandTransport.java:50)
Caused by: java.io.EOFException
	at java.io.ObjectInputStream$PeekInputStream.readFully(ObjectInputStream.java:2325)
	at java.io.ObjectInputStream$BlockDataInputStream.readShort(ObjectInputStream.java:2794)
	at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:801)
	at java.io.ObjectInputStream.<init>(ObjectInputStream.java:299)
	at hudson.remoting.ObjectInputStreamEx.<init>(ObjectInputStreamEx.java:40)
	at hudson.remoting.AbstractSynchronousByteArrayCommandTransport.read(AbstractSynchronousByteArrayCommandTransport.java:34)
	at hudson.remoting.SynchronousCommandTransport$ReaderThread.run(SynchronousCommandTransport.java:48)


The restart process should "gracefully" close slave connections, as to not cause the "SEVERE" I/O errors.
