Mysql problem

["Steve Moran" <steve.moran () csssoftware com>]

I have some rules set up to monitor surfing, which generate a ton of
alerts.  Like 70,000 alerts a day.  The problem is, when I try to
delete, archive, or anything other than view some of the alerts when I
have that many I get a 'Database ERROR:
Database ERROR:Can't open file: 'data.MYD'. (errno: 145)'
 
Anyone else see this with large #'s of alerts?  Or have any idea how to
fix it.
