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
