Jenkins从属设备脱机，并显示消息“错误：连接已终止/连接已终止”

Question

One of our Jenkins slaves went offline with the following message:

ERROR: Connection terminated
java.io.IOException: Connection aborted: org.jenkinsci.remoting.nio.NioChannelHub$MonoNioTransport@5fe56036[name=node-helloworld]

We already restarted the slave and the Jenkins master. Unfortunately nothing helped. Log analysis neither.

Both, master and slave run on Windows Server 2008.

Do you know what could have caused the problem and how it can be solved?

Answer 1

I had the same issue with Jenkins 2.6 on linux. Fixed it by upgrading the java version on the slave from Java 7 to Java 8.
