Bug 560157

Summary:

SELinux is preventing mono (unlabeled_t) "unix_write" to <Unknown>
(unlabeled_t).

Detailed Description:

SELinux denied access requested by mono. It is not expected that this access is
required by mono 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://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.
