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:

To fix this go to the rundeck job, to notifications and under “Average Duration Exceeded” try raising the threshold.

• Rundeck 4.16.0
• Version 2.414.1
