Our system had the bug JENKINS-49745 which creates an obscene amount of Log entries by default in Jenkins.

The sheer number of log entries were negatively impacting the system (large amounts of memory and disk io were being used).

The support core plugin ended up actually making the system unusable when it built its support bundles (zip files) every half hour, eventually killing the system altogether.

I would propose two things:

1. Add a configuration option to turn off the automatic building of support bundles.
2. Have support core be smart enough to not try building bundles when the system is under pressure (and put up a banner on $JENKINS_URL/manage to showing bundles were skipped)
