Description Viess 2010-10-11 12:33:08 UTC
Summary:

SELinux is preventing /usr/sbin/vnstatd "write" access on /var/run.

Detailed Description:

[vnstatd has a permissive type (vnstatd_t). This access was not denied.]

SELinux denied access requested by vnstatd. It is not expected that this access
is required by vnstatd 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.

We probably need to back port this fix to F13.
