I am trying to trace a deadlock that is occurring in our SQL 2005 database (64-bit). We do not currently have snapshot isolation enabled.

I turned on tf-1204 and received the output below.

From this output I am able to determine that Node 1 is a stored procedure that selects data and only modifies values in #temp tables.

Node 2 is another stored procedure does a simple primary key based update on a single row of data.

What I can't determine is the actual resource that was in contention here. The Keys of 10:72057594060734464 and 10:72057594038910976 allow me to determine the database, but these object ids cannot be resolved with object_name. In fact, they should be int values, so I'm not sure where these large numbers are coming from.

In researching the problem I was able to get similar values out of Activity Monitor for Object ID as well.

How do I resolve these object identifiers?

Here is the deadlock tf-1204 output:

These IDs actually refer to hobts (Heap Or Binary Tree), found in sys.partitions. Try the following query inside database 10, and you will find which object and which index is affected.

SELECT hobt_id, object_name(p.[object_id]), index_id 
FROM sys.partitions p 
WHERE hobt_id = 72057594060734464
