[c-nsp] Cisco 4900M Issue

[Jimmy Changa]

Greetings,

I have 2 Cisco 4900M with Port Ten1/7 and Ten1/8 in a port-channel
configuration. Under heavy load (10Gb or higher) I begin seeing a large
number of dropped packets and the following error message in the logs:

%C4K_SWITCHINGENGINEMAN-4-IPPLLCINTERRUPTFREELISTBELOWHIPRIORITYTHRESHOLD:
(Suppressed 281 times)IPP LLC freelistBelowHiPriorityThreshold interrupt

I've never seen this message before, and not much is availible online
(including cisco.com). Has anyone else seen this before? Am I hitting some
sort of limitation with the ports being on the same ASIC or something?

Any insite appreciated.

Thanks in advance.
