Pause Input errors

Hi All,

I have 2 3750-x's in a stack configuration. I have two servers which lost heartbeats with each other a few days a go Each server has each NIC going into one port of the stack.

Gi1/0/9 and Gi2/0/9 which plugs into one of the servers has a large "Pause Input" count which is negative. So looks like:

-231241434 Pause Input
