[c-nsp] GEIP CPU 99%

[Diego]

Hi folk,

    Does anyone know what could cause high CPU utilization on GEIP in Cisco
7513? I found a documentation about Rx-side-buffer which talk about it, but
in my case, I just made a reseating of this module and the CPU utilization
goes down.
Is it a bug or hardware revison problem?

Thanks
