Deadlocks in SQL2008R2 due to DDL triggers. RRS feed

  • Question

  • We used DDL triggers in SQL 2005 for auditing purposes. When migrating to SQL2008R2, these DDL triggers generated deadlocks on system tables.

    Our ETL process starts with launching multiple sub-packages in parallel each creating a number of temporary work objects (tables, views and even stored procedures (?)).  

    There is also a DDL trigger that captures object CUD statements and logs them into a central database.

    create trigger [ddltrig]

    on database




    This worked fine in SQL2005; but generates deadlocks in SQL2008R2 on sys.sysschobjs.

    Disabling the DDL trigger solved our problem.

    Is this a knwn bug in SQL2005R2? Is a bugfix planned? 

    We temporary disabled the DDL trigger and are investigation some build-in auditing options in SQL2008R2.
