For some reason I cannot fathom, cron.hourly runs twice each hour on one of my two CentOS-5.4 systems, as reported in /var/log/cron: ------------------------- Mar 16 14:01:01 helen crond[27833]: (root) CMD (run-parts /etc/cron.hourly) Mar 16 14:01:01 helen crond[27834]: (root) CMD (run-parts /etc/cron.hourly) ------------------------- On the other it just runs once, as expected. ------------------------- Mar 16 13:01:01 althea crond[23373]: (root) CMD (run-parts /etc/cron.hourly) Mar 16 14:01:01 althea crond[23553]: (root) CMD (run-parts /etc/cron.hourly) Mar 16 15:01:01 althea crond[23695]: (root) CMD (run-parts /etc/cron.hourly) -------------------------
This doesn't have any bad effect, but it does run the scripts in /etc/cron.hourly twice.
I just wonder if anyone has come across this curiosity? Or can suggest any possible cause.
