Re: [Openstack-operators] UDP Buffer Filling

Hi Liping, Thank you for the detailed response! I've gone over our environment and checked the various values. First I found that we are dropping packets on the physcial nics as well as inside the instance (though only when its UDP receive buffer overflows). Our physical nics are using the defau
