I have exactly the same problem: dhcrelay uses 100% CPU and not relaying DHCP packets. I have multiple VLANs with Microsoft DHCP Failover setup, this was worked great before 24.1.6, and nothing was changed in config. I am using Hyper-V Server, OPNsense is running in a virtual machine with multiple interfaces. DHCP Guard was not enabled at all.
