[SOLVED] SEVERE hudson.triggers.SafeTimerTask since migration to 2.401.3

Using Jenkins Ask a question
1

Hello,

since I migrated my Jenkins from 2.346.3 to 2.401.3, I have the following error every 30 minutes in my jenkins.log file
I have checked all my pipelines, none of them has a polling period of 30 minutes.

What is it, and how can I get rid of this ?

Thanks in advance

I think I figured out what the problem was :
I went to http://JENKINS_URL:8080/computer/api/xml?tree=computer[executors[currentExecutable[url]],oneOffExecutors[currentExecutable[url]]]&xpath=//url&wrapper=builds
This showed me there was a job running since 3 months, but in Jenkins’s interface, it didn’t seem to use any executor.
Anyway, I succeeded in killing it. Since, I don’t have the error anymore.
