Jenkins is running on a AWS EC2 Server. I caught an alarm shows that the CPU utilization rate was over 98% for 2 mins long and I restarted my Jenkins. The CPU utilization rate did go down but partially my jobs’ configuration was gone. Can’t find config.yml in the jenkins/jobs folder. But some of jobs which I edited recently stayed as the same. So I’m wondering if Jenkins have a trigger to clean old jobs’ configuration when being restarted? Appreciate any help below!
