Bug 627099

Summary:

SELinux is preventing /usr/sbin/upssched "write" access on upssched.pipe.

Detailed Description:

[upssched has a permissive type (nut_upsmon_t). This access was not denied.]

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