InnoDB: Error: trying to load index <FF>the_idx for table db/the_table
InnoDB: but the index tree has been freed!
141126 15:41:02 [ERROR] Cannot find or open table db/the_table from
the internal data dictionary of InnoDB though the .frm file for the
table exists. Maybe you have deleted and recreated InnoDB data
files but have forgotten to delete the corresponding .frm files
of InnoDB tables, or you have moved .frm files to another database?
or, the table contains indexes that this version of the engine
doesn't support.
See http://dev.mysql.com/doc/refman/5.5/en/innodb-troubleshooting.html
how you can resolve the problem.
