Messagedata.MYD is the mysql 'data' file (MYI is the index file). The 'data' file in the snort database schema contains the payloads (and probably should have been called 'payload', not 'data'). One guess, is that you may have hit one of the upper limits for MySQL data size, since it is usually the payload table that grows fastest. One limit is the maximum number of rows per table, you can change this within mysql (either at create table time, or alter table). I can't remember the exact parameter. It's tied up with the idea of average row size. So you can get around this limit. The other limit is that some OS's can't create a file > 4Gb (2^32). Others can. This is not a MySQL limitation, really. But MySQL 3.x can't make a database table spread over a number of files. Not sure whether 4.x can.

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.
