sp_sqlagent_get_perf_counters SQL Server 2005 running every 20 seconds A little background info:

We are running SQL Server 2005 SP2 on a server with Microsoft Windows Server 2003 SP2.

When I run profiler I notice that EXECUTE msdb.dbo.sp_sqlagent_get_perf_counters is running every 20 seconds.

Here is what the profiler is running every 20 seconds:

SELECT N'Testing Connection...'
go
EXECUTE msdb.dbo.sp_sqlagent_get_perf_counters
go


What I have done so far:


I have deleted all the demo alerts on the system.


Possible answers:


I was wondering if a service pack 3 or 4 on 2005 might fix this issue?
or is there something I can set in the registry or in sql itself?
or is there a patch for Windows Server 2003 that might help?
Does it matter, unless it is sucking resources? As I understand it (from some searches), it will run anyway.

There is an MS Connect item for SQL Server 2008 for CPU usage, but it looks unresolved
