I'm experiencing the same problem. Our Foreman host has mmultiple IP addresses (A records) and we use DNS sortlist. Foreman host IP from the subnet from where the DNS request is made is put on the top of the list. Might this be the problem? It worked in 1.8 RC3.

Same issue here, 1.8 release. Can't delete host - can't modify frozen hash. CentOS 7.1

The regression between RC3 and .0 was triggered by the last minute #10020 fix. The issue's coming in when Foreman's deleting the DHCP reservation, which causes it to create one in memory temporarily. To do that, it's trying to resolve the IP address of the TFTP server from a network interface that was just deleted (the "frozen" error). Prior to #10020 it wasn't setting the next-server option at all, so this problem didn't occur.

As a workaround, on your TFTP server (often Foreman), change :tftp_servername in /etc/foreman-proxy/settings.d/tftp.yml to an IP address or uncomment it and set to an IP if unset.
