please paste your current "forwarding-options sampling" configuration.

it could be that you're hitting the built-in rate limit for sampling, or 
maybe your firewall filters aren't working right, or your multipathing 
isn't what you'd want it to be. Do you have an advanced services pic / 
MS-PIC in the m10i? If in doubt, paste a  "show chassis hardware 
clei-models" (clei-models to easily obscure the serial numbers).

Kind regards,

Felix
