Sql Server trace? Who is running it and how to stop it?
Run the SQL command below:

   select
          [Status] =
          case tr.[status]
                when 1 THEN 'Running'
                when 0 THEN 'Stopped'
          end
          ,[Default] =
                case tr.is_default
                      when 1 THEN 'System TRACE'
                      when 0 THEN 'User TRACE'
                end
           ,[login_name] = coalesce(se.login_name,se.login_name,'No reader spid')
          ,[Trace Path] = coalesce(tr.[Path],tr.[Path],'OLE DB Client Side Trace')
          from sys.traces tr
                left join sys.dm_exec_sessions se on tr.reader_spid = se.session_id
