Generically speaking, a throttle occurs when the interface is not able to process any more packets due to buffer or processor overload. To get a better understanding as to what is causing the throttles in your case, we would need to see a complete show interface, show ver, show controller (for that interface), show proc cpu history, and show buffer. It would be good to see these commands a few times when the throttle count is incrementing. The ignores are a further indication of a buffer/processor overload.
