Tom, There are no foreign key references to or from this table as the updates to it consume a large % of the overall DB activity so I kept everything to a minimum. I think Csaba has spotted the real problem but given that changing the order is not that easy and these stats are not mission critical I may just live with the odd deadlock. At least I understand why this is happening now. Thanks, Gavin
