Currently I have this issue within my Jenkins pipeline. Here is the context.
I am setting the Jenkins server in EC2 instance and docker container as an build agent. within this one, I install docker in the same instance with Jenkins and make correct URI, and then it work fine
So I was troubleshooting the pipeline, and after a few run, it showed a weird error that I belive that it not relate to my Jenkinsfile
Here is the error

Aug 12 09:23:03 ip-172-31-3-157.ap-southeast-2.compute.internal systemd[1]: Stopping jenkins.service - Jenkins Continuous Integration Server...
I've noticed in the log is that at which step return above error, it shows this warning WARNING o.j.p.w.f.FlowExecutionList$DefaultStorage#unregister: terraform-cost-estimation#15 was not in the list to begin with: []
I could check in the log and see there are a log that said that "Built-in Node offline due to lack of disk space," but I do the cleanup up in the server, which reduced it to only 47% and also restart the jenkins but did not effect anything
Can you guys help me on this?
Really appreciate for your help. Thank you very much
