Hi Guys,
We have farily stock standard config across our 5Ks as follows however while the port-channel / vPC is UP the server side complains with the following error continiously:

We've updated the kernel and the driver on the said server to no avial. I've also removed and re-applied the configuration on the N5K side - wondering if anyone has run into this sort of issue before and has a fix? From the switch side there doesn't seem to be any additional configuration i require; (correct me if i'm wrong). Any assistance would be appreciated.
thanks
Sheldon
