Odhcpd error in system log

Thu Dec 31 18:25:40 2020 daemon.err odhcpd[2509]: Failed to send to ff02::1%lan@br-lan (Bad file descriptor)

Folks I'm running Kong's build on my R7800, for the last few days I'm getting the error above every few mins in my system log. Really would be helpful if anyone more knowledgeable than myself could shed any light as to what could be causing it.. So I could try and track it down. Thank you
