CB

Row size too large (> 8126). Changing some columns to TEXT or BLOB or using ROW_FORMAT=DYNAMIC or ROW_FORMAT=COMPRESSED may help. In current row format, BLOB prefix of 768 bytes is stored inline.

The above is output when attempting to convert to InnoDB when textarea or editor fieldtypes contain a very large amount of information. For example 10+ paragraphs.
