          SQLDB 2005 
SQL Server 2005 has a default trace running by default. This can be switched
off by using sp_configure i.e.

exec sp_configure 'show advanced options',1
reconfigure
exec sp_configure 'default trace enabled',0
reconfigure

However, this default trace is very lightweight and is very unlikely to be
causing any issues. I would just filter that wait type from you results.
