title: How to stop Jenkins log from becoming huge?
body: <p>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 quickly even to be rotated, and just eats up all my disk space, which then causes various services to fail because they cannot write files anymore.</p>
  
  <p>How do I avoid that?</p>
