1.1.0 is EOLed since Dec 2017. That means that if you encounter a bug,
you're on your own. ISC will not be fixing anything in versions that are
too old. If I were in your position, I'd seriously consider moving to
1.4.0 once it becomes available. It will have a HA support that works
with memfile.

Correct. That's currently under consideration for 1.5. If you are
interested in this functionality and are willing to help fund its 
development and/or test it, please contact me off-line. We do have an 
early description of the solution here:

http://kea.isc.org/wiki/CentralizedConfigNetconf

For various reasons we had to mix two aspects together: configuration 
storage in DB and netconf. If you don't care about netconf, pay 
attention only to the DB sections.

Great to hear about the rock solid part.

The metric fix is coming up in 1.4-beta.
