Unbound fails to resolve sometimes

DHCP hosts not reliably propagated to DNS

I recently set up a new filewall with IPFire, but sometimes hosts that pull a DHCP address don’t get propagated into the DNS server properly. When this happens, if I log into the firewall and do this: # /etc/init.d/dhcp restart …then the host will show up in DNS. My suspicion is that whatever mechanism that the unbound-dhcp-leases-bridge process uses to tell when it should regenerate the table is not working reliably. What can I do to help troubleshoot this?
