KEA DHCP crashed

Qinn

With 2.7.1. release I have switched to KEA DHCP and today it it crashed. The only thing I can trace back (logs have 500 max entries) that service watchdog detected service kea-dhcp4 stopped. Restarting kea-dhcp4 (KEAS DHCP server) and this is repeated so many times that it clogged the logs, until I did a reboot of pfSense.

This may be a similar issue

I support several Netgate appliances with my work. One of the main regional offices hosts a Netgate 8200MAX unit with multiple VLAN's, active DHCP services with many leased IPv4 addresses assigned on each VLAN. The office also hosts many servers / services behind the firewall.

I have attempted to change the DHCP service from ISC DHCP to KEA DHCP however when making the change, the DHCP IPv4 service stops and will not start.

DHCP IPv6 (which is not being used but is enabled) shows the service as working. I have reverted the change back to ISC DHCP and immediately the DHCP IPv4 starts working again.

I will attempt to change the DHCP service from ISC to KEA again soon and will capture logs to see whether the issue can be identified.
