We are running a DHCP server (not a relay) on our Sophos UTM. In the DHCP logsI see every 5 minutes the log below.
It looks like the DHCP server is restarting every 5 minutes. Is this normal? Why every 5 minutes?
Thanks, Richard

And then 5 minutes later exactly the same messages. Is this normal operation?
