Mysql question

I have a site using PHP & Mysql. About a month ago to now one of the tables gets corrupted with the message Got Error 127... I fix it and everything works OK, except every time I loose 1 record. Today I could obtain mysql.err from the machine and I could see whenever an error is produced by date, previously I have the following line: 020205 9:57:46 Aborted connection 137 to db: 'Biblioteca' user: 'ODBC' host: `localhost' (Server shutdown in progress) 020205 9:57:46 Aborted connection 124 to db: 'Biblioteca' user: 'ODBC' host: `localhost' (Server shutdown in progress) or 020205 12:55:51 Aborted connection 377 to db: 'Biblioteca' user: 'ODBC' host: `localhost' (Unknown error) 020205 13:05:37 Aborted connection 504 to db: 'Biblioteca' user: 'ODBC' host: `localhost' (Unknown error) It doesn´t seems too clear for me because no ODBC client should be accessing to the database. Should I suppose that an unautorized ODBC client is breaking the table or could be another problem? Thanks a lot. Emiliano.
