From: Vyacheslav Yurkov <[email protected]> ISC DHCP should link against BIND9 libraries, which are tailored specifically for DHCP. BIND9 package in Yocto core layer has different configuraiton, in particular it has threads and epoll enabled.
ISC DHCP isn't a multi-threaded application, running it with bind9 libraries compiled in with threading enabled is not something ISC can vouch for. BIND9 libraries support a lot of options specifically geared towards optimizing DNS operations, many of which do not play nicely with ISC DHCP's "architecture". It isn't necessarily practical to build those libraries for both purposes. If threading is enabled, then DHCP sporadically fails/crashes with messages like: lib/isc/unix/socket.c:1054: epoll_ctl(DEL), 6: Bad file descriptor lib/isc/unix/socket.c:3332: INSIST(!sock->pending_send) failed.
