the input error with giant this may be because of other side of link use MTU higher than 6000 side.
check that.

Thank you. I am checking now,
but what about the other port with no giants, would that also be affected by the MTU setting?...

clear the counters and see how fast they increasing :
how is the utilisation of the port ? is this only 1 port / port-channel or all interfaces ?
