Github user swill commented on the issue: https://github.com/apache/cloudstack/pull/1549 This was shared in the "4.9/master Testing Coordination" thread. Simon Weller and his team at ENA have run into this on the latest master in both of their hardware labs while testing master for me in preparation for the 4.9 RC. I am still getting the `addHost` issue periodically which showed up a lot when this had bigger issues. I am concerned about this in production to be honest. How long has this been running in production at your client?
