Hi thanks for your reply. I think I am reading the XML incorrectly. I had thought that the code in the Input Buffer was the one executing during the deadlock.

In this case for both SPIDS it says that Proc [Database Id = 7 Object Id = 1003150619] was the code running. This is a Stored Proc called proc_MSS_ProcessComitted.

So am I wrong in thinking then that at the time of the deadlock both SPIDS were executing proc_MSS_ProcessComitted and it is that that requires the investigation?

Any help on actually reading the Execution Stack would be helpful as its really confusing to me.

Thanks
