22.1.9 DHCP issues

[MiRei]

With version 22.1.9(_1) our DHCP-V4 server crashes permanently. The hanging DHCP process could only be terminated via the console with kill -TERM $PID.
Only a downgrade with opnsense-revert -r 22.1.8 isc-dhcp44-server could restore stable operation.

We use an HA configuration. This behaviour was identical on the MAster and the slave.

Best regards
