A deadlock can occur when two transactions are trying to use the others’ resources and SQL Server can’t decide which transaction to run first. Enable it by either issuing the command DBCC TRACEON (1222,-1) or inside SQL Server Configuration Manager, select the SQL Server instance and add -T1222 to the startup parameters.
