[c-nsp] Odd Network Issue (7600/Sup3BXL)

[Devon True]

Twice in the past two weeks, a Cisco 7600 router with a Sup3BXL has 
stopped egress traffic from a port on a WS-X6708-10GE module to one of 
our Internet providers. All other circuits on the same WS-X6708-10GE 
module are fine. BGP with the provider never goes down, however 
bandwidth drops from ~500 Mbps to < 1 Mbps. During the second event, I 
looked at the CEF table for the interface and I saw the appropriate 
entries. I had to restore traffic levels by shutting down BGP with the 
provider.

I have a ticket opened with Cisco TAC, but has anyone seen this issue 
before?
