No idea on the cause, but sitting with the exact same issue on 1 specific
MyISAM table on mysql-5.1.50
Since the table was created it never had any change in data structure, the
table is almost exclusively INSERTs and it is quite big in my instance
however. Table crashes on average every 2 to 3 days for no apparent reason
what so ever, and everytime it repairs successfully...
