I don't understand where to dig.
I have increased numbers of input errors and same numbers of ignored. Is it problem with cable or another problem?
At the other side of cable ( ASA 5510) there are no errors.
416 input errors, 416 ignored

Hello Mike,
here is the definition of ignored
Shows the number of received packets ignored by the
interface because the interface hardware ran low on internal
buffers. These buffers are different from the system buffers
mentioned previously in the buffer description. Broadcast
storms and bursts of noise can cause the ignored count to be
increased.
you can try to increase the input hold-queue to see if they stop to increment
int f4/1
hold-queue 1024 in
However, they are less then 0.1% so they shouldn't cause performance issues
Hope to help

Hello!
Unfortunatly it didn't help...
Why do you think i need to increase that queue.
From output
Input queue: 0/1024/0/0 (size/max/drops/flushes)
seems 0 drops or i missunderstood it?

Hello Mike,
it was a try.
There is a chance this is just noice of some protocol not active/not known on this interface.
Hope to help

I found where was problem.
I have service-policy input XXX at that interface.
Errors disappeared after remove that.
