A deadlock was detected while trying to lock variable "User::CollectionPackageName" for read access.

    New to using Data Collectors on SQL 2008, I'm pulling my hair on this one.
    First here is the error I'm getting on the collector the second time it tries to run the T-SQL Query Collector item when I change the set's Perfmon collector item from what's in the main set to the set below it:
    A deadlock was detected while trying to lock variable "User::CollectionPackageName" for read access. A lock could not be acquired after 16 attempts and timed out.
    This is the Collector Set that works just fine, but when I replace the Performance Counters xml with the XML at the bottom of this post, then the mayhem ensues. The second time the collector is triggered, the T-SQL portion will fail with above error.

    @ErrorProcedure = ISNULL(ERROR_PROCEDURE(), '-');
    RAISERROR (14684, @ErrorSeverity, 1 , @ErrorNumber, @ErrorSeverity, @ErrorState, @ErrorProcedure, @ErrorLine, @ErrorMessage);

    End Catch;


    This is the counter set to replace above that creates the error, and yes, I do have these defined in my system:

    Thanks in advance!

    What I ended up doing was breaking up the collector set into two seperate collectors and that fixed it. This is only a workaround though as the full collector with both items should work.

    I believe this have been reported on Connect site, I will chase up the post with MS.
