Brady, I'm curious - does enabling a-mpdu support disable a-msdu support? Given that a-msdu aggregation does not supply a header and checksum for each frame might explain the performance problems.

Thanks Diana, we'll give that a try. I had found a controller setting that seems to have made the problem occur much less often, though I'm not willing to say it "fixed" it. For whatever reason, our controllers had "802.11a 11nSupport a-mpdu tx priority 0 disable" in their configuration, and reversing this with "enable" made our 5100 problem far more difficult to reproduce.
