We have had to blissfull days of stable Jenkins. Today two nodes are disconnected and they will not come back online.
What is strange is it is the same two-three nodes every time. Running disconnect on them through the URL http://jenkins.example.com/jenkins/computer/NODE_NAME/disconnect, does not work. I have to enter configuration, Save, then relaunch to get them up running. I tried setting the ulimit values as suggested in https://support.cloudbees.com/hc/en-us/articles/222446987-Prepare-Jenkins-for-Support#bulimitsettingsjustforlinuxos I have also added additional JVM options as suggested in https://support.cloudbees.com/hc/en-us/articles/222446987-Prepare-Jenkins-for-Support#ajavaparameters https://go.cloudbees.com/docs/solutions/jvm-troubleshooting/ The number of threads of Jenkins server is currently 265. Yesterday when all was fine this was up to 300. Maybe ralted or unrelated: When this happens we have some builds on other nodes that stops working. They are aborted, but are still showing as running. The only thing that works is deleting the agent and creating it again, that or restarting Jenkins. søndag 14. juli 2019 13.31.51 UTC+2 skrev Sverre Moe følgende: > > I suspected it might be related, but was not sure. > > The odd thing this just started being a problem a week ago.
