[c-nsp] excessive buffer overrun/ignored packets on GEIP+ interface

[Carlos Kamtha]

Configuration is as follows:


7507 w/GEIP+ --------> Cat6509 (MM fibre)

Sometimes, (not always) I get tons of packet loss on the link. a show interface
shows a gross amount of 641521 overrun, 16211710 ignored errors. 

There are no more errors on the interface. 

I had initially cleaned the fibre and that seemed to help the problem, but recently
it has resurfaced.  

I also bumped up the in/out hold queue to the max on the interface, in hopes that would
help but so far no luck. 

I have plenty of headroom on the link, so it isnt a BW availability problem. 
 
Anyone have any experience with this type of problem?

Carlos.
