How to stop Jenkins log from becoming huge?

Question

Recently my jenkins.log has started getting very large, very quickly, full of exceptions about DNS resolution. I attempted to use logrotate, but the log file grows too quick

Answer 1

For the ones using Centos/Redhat, the option to disable the DNS Multicast feature can found in /etc/sysconfig/jenkins

JENKINS_JAVA_OPTIONS="-Dhudson.DNSMultiCast.disabled=true -Dhudson.udp=-1 -Djava.awt.headless=true"
