+# Because of the high debug level enabled for LRC daemons, the root drives
+# fill up rather quickly.  The drives fill up before the daily logrotate can
+# run so we rotate every 6 hours and keep 3 days worth.  This can be adjusted
+# as needed.  Logrotate already runs daily at 06:25 so there are 3 additional
+# scheduled cronjobs to rotate 4x daily.
