Hi I Enabled Server Side Profiler for a database. in events I choose "Blocked process report" with threshold = 5 for totaly 2 hours in every days. But the question is :some times most of the cause of blocking is an SP that only contain a select with readuncommitted ???is it possible ?why ? and interesting point is on xml filed (bpreportxml) for secondary part (<blocking-process>) we dont have any sql line that have sqlhandle . then we can not find the table and index related to this sp .
