when looking at a gigabitethernet interface i found that it's experimenting output errors. i was wondering exactly what could cause this and how to fix it. as far as i know having output errors on a GE is not posible wihout having underruns. anybody can explain to me what an output error means?

Sum of all errors that prevented the final transmission of datagrams out of the interface being examined. Note that this might not balance with the sum of the enumerated output errors, as some datagrams might have more than one error, and others might have errors that do not fall into any of the specifically tabulated categories.
I would look at a burst of traffic hitting the interface and filling the Rx ring hence causing drops. The burst of traffic is too much for the interfasce to handle so it drops the packets .
