have you check to see if some basic alert is causing it? To get to basic alerts, you have to open the old windows fat management client and go to basic alerts there.
If you run these query, then you might be able to narrow it down.
Where [Extra1] like 'Orion Alert'
If something was returned, run:
Where AlertID = 14
Where [Parameter1] like '%Orion Alert%'
If something is returned on this, run:
where AlertDefID = '<what you got back>'
