Hi Pravin, Thanks. Does this mean it is a confirmed bug? How would I be able to get the patch and install it into our environment? Thanks, Uri On Sat, Jan 7, 2017 at 1:01 PM, Pravin Shelar wrote: > Thanks for all investigation. > > On Sat, Jan 7, 2017 at 12:57 AM, Joe

Hey Joe, I agree with you. It dumbfounded us that a single packet could kernel panic a host so easily and in fact made me believe for at least a few days that this was a red herring. The fact that we cannot replicate it and randomly occurs (within a given time period) also makes it impossible

[ovs-dev] ovs-vswitch kernel panic randomly started after 400+ days uptime

Hi, Since about 10 days ago, every few hours, one of our 10 compute nodes on our Openstack cluster kernel panics at the host level kernel panics (captured through netconsole). The kernel panic is identical across all 10 nodes and happens at random times but at least 1 node kernel panics every
