As this remains an issue for me, I'm reposting. Please forgive the redundancy, but I've been unable to find the answer and am hoping for some guidance.
OK, are you running named in a chroot env?
============================================= Aug 16 07:12:23 sunspot setroubleshoot: SELinux is preventing /usr/sbin/named (named_t) "getattr" access to /dev/random (tmpfs_t).

Have you done the above to get the complete message?
Hi Robert,
Yes, to both. My original post contained the output which is also here (below) for ease of review:
Any suggestions would be greatly appreciated
Kind regards, ~Ray

[root@sunspot ray]# /usr/bin/sealert -l b7014747-0d8d-443e-8b9a-af868976452d Summary SELinux is preventing /usr/sbin/named (named_t) "read" access to random (tmpfs_t).
Detailed Description SELinux denied access requested by /usr/sbin/named. It is not expected that this access is required by /usr/sbin/named 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. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.
Allowing Access Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for random, restorecon -v random. There is currently no automatic way to allow this access. Instead, you can generate a local policy module to allow this access - see http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 - or you can disable SELinux protection entirely for the application. Disabling SELinux protection is not recommended. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package. Changing the "named_disable_trans" boolean to true will disable SELinux protection this application: "setsebool -P named_disable_trans=1."
The following command will allow this access: setsebool -P named_disable_trans=1
