Got it. If we stick to 1.4.6 kernel, is there any parameter we can tune to mitigate the situation? Many thanks! Jian Qiu On Tue, Aug 20, 2013 at 9:00 AM, Jesse Gross wrote: > On Mon, Aug 19, 2013 at 4:45 PM, Jian Qiu wrote: > > Jesse, > > > > Thanks for your quick response. > > > > Which v

Jesse, Thanks for your quick response. Which version would you recommend upgrade to? As you know, this is our production environment, stability is the first priority. May I upgrade the userspace programs only? We might not be able to upgrade kernel module as replacing kernel module may require a

Hi, I run two bridges on my openvswitch (ovsbr0, ovsbr1) both have redundant ports (bond0, bond1 with lacp) since the port groups have different performance (1gbs and 10gbs). Multiple internal interfaces are connected to the bridges and get network traffic assigned based on the vlan tag. Since
