Could this be the long-standing bug that hangs raid5 and raid6 reshapes? I don't remember it being found and fixed. iirc (it's too long ago) it hit people adding a drive to a raid5 (occasionally a raid6), and was fairly easy to get round. Again it's too long ago but stopping and starting the reshape fixed it usually iirc.
