I remember having a similar issue a few years back in an older  
openstack release, probably Ocata. We had difficulties loading *all*  
instances in the admin tab in Horizon dashboard. It turned out to be a  
memcached misconfiguration. I don't recall the details, unfortunately.  
But I'd start with memcached.
