I got a core dump of certmonger failing user abrt but it's huge. Is there any 
particular part that would be useful.

In /var/log/messages I get

This is the first error I get in /var/log/httpd/error_log when I try to delete 
a host

Yes ipa cert-show 1 does show the same thing
# ipa cert-show 1
ipa: ERROR: Certificate operation cannot be completed: Unable to communicate 
with CMS (Service Unavailable)

I'm sure SELinux is not an issue. There are no AVC errors in 
/var/log/audit/audit.log and it fails the same way in 'Enforcing' and 
'Permissive' modes

I'm pretty certain the dogtag service is not running
