      When an instance has gigabytes of GC log files, the support bundle generator can effectively take forever. This not only causes high load for Jenkins, but can prevent from generating a support bundle.

      Steps to reproduce

      1. Add 100's GB of log files to the GC folder (specified in JVM startup flags)
      2. Try to collect a Bundle

      Expected Behavior: The bundle is generated in a reasonable amount of time and just includes the most recent data from the GC logs instead of trying to include all of them.

      Actual Behavior: You will see that the bundle collection times out or runs forever.

          It is usually up to the admin to set up a rotation process (such as logrotate or a cron) although it would be useful to limit this in support-core to avoid performances issues when generating the bundle or producing huge bundles.

          A time limit might of the last 48 hours might be a good start. We could make this configurable via a system property.

          I see this ticket as an Improvement, not a bug. It's logical that it takes a long time to gather the files if GC log is huge. WDYT egutierrez?
