Lame switches with too-small buffers.

Turning *off* qos will reduce the amount of drops you see (what qos does
is "take tiny buffers, spread over 4 different queues, and all of a
sudden your traffic only has 1/4th the buffer space available").

Alternatively, you could fiddle with qos to give all buffers to 
a single queue, and put all traffic in that queue, but that's 
effectively turning it off...
