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. Vyacheslav
