    Hello again Grant

    Heres what i am finding.

    The alert for hash warnings is showing up against server 15 and in the Master database.

    I click on 'overview', then my server (server15), then 'local' and that brings up the databases on the server, then i click on 'master' and change the time to the required time when the alert happened (in this case 04:28).

    When i look at the query text at the bottom the first query is this :

    SELECT cntr_value

    FROM sys.dm_os_performance_counters

    WHERE object_name = CASE WHEN SERVERPROPERTY('InstanceName') IS NULL

    THEN 'SQLServer'

    ELSE 'MSSQL$'

    + CAST(SERVERPROPERTY('InstanceName') AS VARCHAR)

    END + ':SQL Errors'

    AND instance_name = 'User Errors'

    From query plan: 0x060001001847c40140a18482000000000000000000000000

    *****************************************************************

    Another one of the queries reads:

    SELECT cntr_value

    FROM sys.dm_os_performance_counters

    WHERE counter_name = 'Cache Pages'

    AND instance_name = 'SQL Plans';

    From query plan: 0x060001009877e62440a1a082000000000000000000000000

    The querys dont seem to correlate to the things we run - How are these being generated ?

    Those queries are being run by SQL Monitor. Neither is especially egregious in any way (and we have a couple of queries I'm not happy with, but not these). Other than the fact that they're not your queries, were these using excessive amounts of resources or running for long periods of time?
