It's trying to replay a transaction that appears to be invalid because the .2 clone is smaller than it thinks. Is this the first time the OSD crashed, or did it crash once, and you cranked up logs and generated this one? If you have the previous log, that would be helpful... it should have a similar tranasction dump but a different stack trace. Also, are any of the 6 patches on top of 0.40 related to the filestore or osd?
