SELinux is preventing /usr/bin/tor "create" access .

Detailed Description:

[tor has a permissive type (tor_t). This access was not denied.]

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

Fixed in selinux-policy-3.7.19-18.fc13.noarch

I think tor is attempting to send a syslog message.

Yeah, I think so as well.  Thank you!
