After rebooting master dc, bind9 will not start automatically.
Error posted in systemctl status bind9:
loading configuration: shutting down exiting (due to fatal error)
…/…/…/bin/named/client.c:3516: unexpected error: isc_socket_accept () failed: shutting down
bind9.service: Main process exited, code=exited, status=1/FAILURE
Failed to start BIND Domain Name Server with samba4 backend.
samba_dlz: shutting down
If I manually start the service, everything loads correctly. Seems bind9 starting too quickly before samba4. Is there anything I can do to fix the issue?
