I just upgraded to SSC 3.1.0.4829 and I am getting frequent calls to this type of execution:
declare @p1 datetime
set @p1='2012-11-15 21:30:26.057'
exec tempdb.dbo.RG_WhatsChanged @SinceWhen=@p1 output,@DatabaseList=N'<stringarray><element><seqno>1</seqno><item>eFR5010Dev</item></element></stringarray>',@Quietly=0,@MatchCountLimit=3
select @p1
It is running for 10-11 seconds, burning 420K reads and eating 20-40% of my CPU. Prior version did NOT do this!!!
I am using SQL 2008R2 and SSMS build is 10.50.2796.
Code storage is Vault 5.1.2
***************************
separate issue: I traced THOUSANDS of calls like this when I went to view history:
exec dbo.spgettxhistory @objid=4309,@rowlimit=1,@begindate='2011-10-02 14:28:28.397',@enddate='2011-10-02 14:28:28.397',@startversion=0
go
exec sp_reset_connection
go
exec dbo.spgettxhistory @objid=4309,@rowlimit=1,@begindate='2011-10-02 14:28:28.397',@enddate='2011-10-02 14:28:28.397',@startversion=0
go
exec sp_reset_connection
go
exec dbo.spgettxhistory @objid=4309,@rowlimit=1,@begindate='2011-10-02 14:28:28.397',@enddate='2011-10-02 14:28:28.397',@startversion=0
go
exec sp_reset_connection
go
exec dbo.spgettxhistory @objid=4309,@rowlimit=1,@begindate='2011-10-02 14:28:28.397',@enddate='2011-10-02 14:28:28.397',@startversion=0
go
exec sp_reset_connection
go
exec dbo.spgettxhistory @objid=4309,@rowlimit=1,@begindate='2011-10-02 14:28:28.397',@enddate='2011-10-02 14:28:28.397',@startversion=0
go
exec sp_reset_connection
go
exec dbo.spgettxhistory @objid=4309,@rowlimit=1,@begindate='2011-10-02 14:28:28.397',@enddate='2011-10-02 14:28:28.397',@startversion=0
go
that sure looks like an infinite looping bug... _________________ Kevin G. Boles
