Basically since the "Current Process" mentioned was the queue on igb5, I ru= n a lagg0 interface with LACP and currently have 4 NIC's within the aggregation {igb2 through 5} connected to a Cisco switch running EtherChannel. On some occasions it seems that igb5 starts flapping too, according to the system logs; not sure if that's related to the issue or not? If I need to post any more information please advise!!
