One of the dbmail is getting delivered thousands of time. Same recipient, same subject , same body.
I know its happening from dbmail. When i do select count(*) from sysmail_mailitems. I see number increasing.
Any idea why this is happening. I am sure that there is no process which is attempting sending multiple times.

SELECT M.mailitem_id
     , M.profile_id
     , M.recipients
     , M.subject
 --    , M.body
 --    , M.body_format
     , M.send_request_date
     , M.send_request_user
     , M.sent_account_id
     , M.sent_status
     , M.sent_date
     , M.last_mod_date
     , M.last_mod_user
FROM sysmail_allitems M
WHERE sent_date > DATEADD(dd, -7, GETDATE())
ORDER BY sent_date DESC;

This will give you an idea which account is sending the emails using which profile.

Maybe that gets you started.

Extended events may also help you out !

CREATE EVENT SESSION [DBA_Track_sp_send_dbmail] ON SERVER 
ADD EVENT sqlserver.module_start
(
    SET collect_statement=1
    ACTION
    (
        sqlserver.client_app_name,
        sqlserver.database_name,  
        sqlserver.session_server_principal_name,
        sqlserver.username,                     
        sqlserver.sql_text,
        sqlserver.tsql_stack
    )
    WHERE 
    (
        [object_type]='P ' /* The space behind P is necesssary */        AND [object_name]=N'sp_send_dbmail'
    )
)

Did you check the content of sysmail_faileditems and sysmail_event_log in msdb ?

Don't be so sure. We had a similar problem with a "wonderful" web service that someone wrote that copied single row "files" from one machine to another. Due to a flaw in the logic, it would lose it's mind every once in a while and copy the same file quite literally a million times in a 24 hour period.

I do like Johan's extended event to find the source of this issue, whether internally or externally triggered. If, for some reason, that doesn't help then, as a last resort, you could also do the BSOFH thing to the problem. Turn off the mail and see which processes fail so that you know where they're all at.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
