We have a large number of jenkins slaves setup vip jenkins-swarm plugin(auto-discover the master)
Recently, we started to see slaves going offline and existing jobs get stuck. We fixed it with restarting the master. However, it has been happening too frequently. Everything seems to be fine, no network issue nor gc issue.
Anyone?
On the jenkins slaves, we see this repeatity once the node become unavailable:
Retrying in 10 seconds
