I was to try to spend some time figuring this this out this weekend, but after updating to 2.6.39.1 for other reasons the problem seems to have been resolved and I can no longer produce it. I can't see anything in the changelog that might be the reason for this, but I'm wondering if it might be the client (ubuntu natty) that was triggering the issue. If it does start happening again I will be sure to get some packet captures. This is just a message for people with similar problems going through the archives.
