Yes, I have. It partially solves the issue. At least DHCP doesn't 
crash/fail anymore, but warnings from epoll enabled are still seen in 
the logs. The other question is do we have to strip down BIND 
functionality in order to make DHCP work?

I understand that maintenance effort is at stake and we are looking for 
the best possible solution here, but IMHO having one set of bind 
libraries for both BIND and DHCP servers is not one of them.

We could also go Ubuntu way here, by having two bind-9.11.x for DHCP and 
upgrading BIND server to the latest stable (9.16.x if I'm not mistaken). 
Then security support could be only done for 9.11.x version, the latest 
stable should have most of security patches included already.
