Just updated a couple of my CentOS to latest version 6.7 via yum (official repository) and since then i am experiencing problems with cron while executing cron.hourly scripts. It seems that the run-parts program starts twice some scripts in the cron.hourly folder.
From cron log i can see (look at the mailgraph script):
Aug 7 22:01:01 spam run-parts(/etc/cron.hourly)[8066]: starting mailgraph
Aug 7 22:01:01 spam run-parts(/etc/cron.hourly)[8180]: finished crm114_cleanup.sh
Aug 7 22:01:01 spam run-parts(/etc/cron.hourly)[8067]: starting mailgraph
Aug 7 22:01:02 spam run-parts(/etc/cron.hourly)[8194]: finished mailgraph
Aug 7 22:01:02 spam run-parts(/etc/cron.hourly)[8066]: starting rules.php
Aug 7 22:01:02 spam run-parts(/etc/cron.hourly)[8203]: finished mailgraph
I see the script mailgraph that is started twice, before the first one ends and this causes an error to the script itself.
I have this situation on different machines, since the last upgrade to latest CentoS 6.7. All installations with CentOS 6.6 are working ok.
Any idea? thanks
