Blocking Locks mystery

  • We have some issues with our Sql server (for 30 minutes CPU usage ~100%) with 2 databases- DB1 and DB2. From CurrentActivity window I see a lot of applications connected to DB1, but in pretty long (60 items) blocking lock list (sp_blockinglocks) I have DB1 as DB name and PK_tbl2 as resource object name, where tbl2 belongs to DB2. How it can be? I checked dependencies, stored procedure, etc. Nothing exists that point from DB1 to tbl2 in DB2. I appreciate any tips. Thanks

  • sure sp_blockinglocks is written alright? (can't find it in the books online)

  • It's not from MS-taken from Kalen's InsideSQLServer website. Search Internet

  • Check the sp_blocker_pss80 procedure from Microsoft PSS

    This will give you more idea on what is going on.
