Description

Since the upgrade to ISC dhcpd 4.3 in 2.3x, several users have reported missing hostnames in the dhcpd.leases file. There is something to it, clients that send a hostname don't always have that hostname end up in the leases file. Not immediately apparent what triggers the issue though. Happens across a wide range of devices with no apparent consistency.

this is a bug with the dhcp-cache-threshold feature.

disabling that has been confirmed to work around the issue by multiple people. Pushed that change as a workaround.
