Issue with a certain java library causes writes of hundreds of GBs in logs Solution is to run jenkins without DNS function
In /etc/default/jenkins add these 2 options in JAVA_ARGS line:
-Dhudson.DNSMultiCast.disabled=true -Dhudson.udp=-1
Restart jenkins:
service jenkins restart
If Jenkins is integrating with rundeck you might get this error on triggering rundeck job:
Waiting for Rundeck execution to finish... Rundeck execution #31579 finished in null, with status : average-duration-exceeded FATAL: Unexpected executions status: average-duration-exceeded java.lang.IllegalStateException: Unexpected executions status: average-duration-exceeded at org.jenkinsci.plugins.rundeck.RundeckNotifier.notifyRundeck(RundeckNotifier.java:299) at org.jenkinsci.plugins.rundeck.RundeckNotifier.perform(RundeckNotifier.java:165) at jenkins.tasks.SimpleBuildStep.perform(SimpleBuildStep.java:123) at hudson.tasks.BuildStepCompatibilityLayer.perform(BuildStepCompatibilityLayer.java:80) at hudson.plugins.promoted_builds.Promotion$RunnerImpl.build(Promotion.java:468) at hudson.plugins.promoted_builds.Promotion$RunnerImpl.doRun(Promotion.java:405) at hudson.model.AbstractBuild$AbstractBuildExecution.run(AbstractBuild.java:526) at hudson.model.Run.execute(Run.java:1900) at hudson.model.Run.run(Run.java:1854) at hudson.plugins.promoted_builds.Promotion.run(Promotion.java:317) at hudson.model.ResourceController.execute(ResourceController.java:101) at hudson.model.Executor.run(Executor.java:442) Finished: FAILURE
To fix this go to the rundeck job, to notifications and under “Average Duration Exceeded” try raising the threshold.
