This may very well be normal behaviour. As soon as there are more than two devices in a stack, the entire stack switches to half-duplex. This is logical while the interconnected GBICS are on a bus-type network. No full-dup here!
As with conventional ethernet, a certain amount of collisions is normal. If they are extensive, you may have a hardware issue. If the collision rate is roughly between one on 10^6 and 10^4 there is not much to complain.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
