br-int not responding after few hours
I have a working multinode icehouse and everything is ok except the dhcp that is not responding after a few hours, when I check tcpdump on br-int that where the dhcp is going throw, there is no traffic at all.
the work around is to restart the network node and everything is working again including the dhcp and traffic is going throw br-int
does anyone encounter an issue like that?
