Cisco BUG - PIM join does not make it to CPU

Cisco BUG

CSCue52328 Bug Details
PIM joins for some groups not processed at CPU level
Under very rare conditions PIM joins from a downstream switch are not forwarded my mcastfwd to PIM
to be processed. This has been seen under the following conditions

a) Downstream device sending PIM joins is a Arista switch
b) There is a local receiver sending IGMP joins for the same group for which PIM joins are received
c) Exact trigger is unknown at this point, could be the remote receivers (which result in PIM joins)
