In that case, it appears that the filesystem on disk gets subtly corrupted, and the only remedy is to destroy it on the receiving machine and start all over (making sure to disable automatic snapshots this time). "zfs receive -F" will rollback snapshots made on the receiving system that don't exist on the sending system, but it only does this at the beginning of the stream -- it can't prevent further snapshots from being taken during reception of an incremental stream which foul up the works. -GAWollman
