I am trying to setup 4 RHEL machines in jenkins as build executors. But the systems are getting disconnected so frequently. I have checked the following points already. Still no luck

  1. Network problems between master and slave
  2. Slave server availability
  3. Slow response from slave (disabled Response time in Manage Jenkins > Manage Nodes > Configure > Response time)

I am getting the following error everytime

  • yes, it disconnects frequently on mac machines; I wonder whether there is some infrastructure to get system event for disconnection, at least... – Nikita Apr 25 '22 at 10:32
  • actually there is this one: https://wiki.jenkins-ci.org/display/JENKINS/Mail+Watcher+Plugin – Nikita Apr 25 '22 at 10:50
