Arlen Rick created an issue   Jenkins / JENKINS-55251 Builds randomly stuck and fail for the reason of lost connection but the slave is actually online Issue Type: Bug Assignee: Jeff Thompson Attachments: plugins_info.yaml Components: remoting Created: 2018-12-19 04:24 Environment: Master: Jenkins ver. 2.138.2 on Ubuntu 16.04.3 LTS (Xenial Xerus), Java 1.8.0_191 Slave: Unix slave, version 3.25 on Centos 7.5,Java 1.8.0_144 Priority: Major Reporter: Arlen Rick The master is installed with an offline installation package. Tasks are all run on physical machines and are written using declarative pipeline. The browser is Google Chrome 70 I tried UNIX SSH and JNLP - Slave to connect the master node and the slave node, which will cause this phenomenon, but it is slightly different. When using UNIX SSH, the node is still online after the build is interrupted. However, using JNLP - Slave method, the node is not online after the construction interruption ( agent.jar process hangs up ). The construction task reported an error as follows:   wrapper script does not seem to be touching the log file in /var/lib/jenkins_node/workspace/FDS/FDS-FdsWebServer-deploy-test@tmp/durable-5927b140 (JENKINS-48300: if on an extremely laggy filesystem, consider -Dorg.jenkinsci.plugins.durabletask.BourneShellScript.HEARTBEAT_CHECK_INTERVAL=86400) [Pipeline] stash Error when executing always post condition: hudson.remoting.ChannelClosedException: Channel "unknown": Remote call on JNLP4-connect connection from 10.0.100.106/10.0.100.106:52594 failed.
