From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.2.17-14smp i686) After upgrading to version 3.0.1-61, I noticed that when a job runs just before 00 seconds, it will be run again at 00 seconds. A typical /var/log/messages entry is: Apr 16 19:00:59 holly CROND[3243]: (root) CMD (run-parts /etc/cron.hourly) Apr 16 19:01:00 holly CROND[3245]: (root) CMD (run-parts /etc/cron.hourly) Reproducible: Always Steps to Reproduce: 1. Search /var/log/messages for cron entries running on 59 seconds, using a search string of ':59 '. First observed in bug number 29160 (Package does not automatically restart crond after upgrade). Posting as a new bug. The problem seems to me to have been introduced by patch 15 (vixie-cron-3.0.1-time.patch). I think the problem is caused by moving the call to 'cron_sync()' into the main loop of the program and relying on 'cron_sync()' to provide the 60 second increment to 'TargetTime'. The problem is that if 'cron_sync()' is called early (i.e., at 59 seconds), it adds 1 second instead of 60. A quick fix would seem to be rebuilding vixie-cron-3.0.1-61 with Patch 15 commented out.
