Description Bram Godod 2009-11-18 18:07:31 UTC
Summary:

SELinux is preventing dbus-daemon (system_dbusd_t) "mmap_zero" system_dbusd_t.

Detailed Description:

SELinux denied access requested by dbus-daemon. It is not expected that this
access is required by dbus-daemon 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.
