Since no one developed a reproducible test case it is, unfortunately, difficult to say whether this bug is resolved. We moved to a 2.6.35 series kernel and stopped seeing this particular problem (although we have seen other problems that are eerily similar). All of the information to reproduce the behavior is in the comments above, but it does take a lot of time and patience to trigger it. Either that, or hundreds of instances running with production load.
