Resolution
The performance issue you are facing might be produced by an administrator executing a Groovy script under Manage Jenkins -> Script Console. Before moving into a different hypotesis, it is suggested capturing thread dumps next time the issue is exposed and ensure that there is not any /script
request into the threads. You can execute thread dumps by following the KB article Required Data: Jenkins: High CPU On Linux
- specifically through the script collectPerformanceData.sh
.
If you would like to disable the access to $JENKINS_URL/script
then you could use the CloudBees Request Filter Plugin.
