| When we updated the plug-ins on Jenkins we noticed that builds were running, would complete their work, but would then stay in the queue after completion with stripes. The queue would then build up and not be processed. It seems like Jenkins lost contact with agents. We have over 200 agents at peak use and 7 EC2 agent profiles currently. We don't know the cause, but upgrading to Jenkins LTS 1.150.1 did not fix it, but downgrading Amazon EC2 plugin from 1.41 to 1.40.1 restored service and allowed our queue to complete. |
