Summary: SELinux is preventing /usr/sbin/crond "sigchld" access . Detailed Description: [SELinux is in permissive mode. This access was not denied.] SELinux denied access requested by crond. It is not expected that this access is required by crond and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug report.

Any idea of why a cron processes is executing shutdown?
I leave my box running during the day but do not want it running all night. I have a root cron task running at 10.15 to shut the machine down. Been doing this for years!
Ok I will add this access. Fixed in selinux-policy-3.7.19-18.fc13.noarch
