 14.4.7 Errors That May Occur When Using `BDB' Tables
 ----------------------------------------------------
 
    * If the following error occurs when you start `mysqld', it means
      that the new `BDB' version doesn't support the old log file format:
 
           bdb:  Ignoring log file: .../log.XXXXXXXXXX:
           unsupported log version #
 
      In this case, you must delete all `BDB' logs from your data
      directory (the files with names that have the format
      `log.XXXXXXXXXX') and restart `mysqld'.  We also recommend that
      you then use `mysqldump --opt' to dump your `BDB' tables, drop the
      tables, and restore them from the dump file.
 
    * If autocommit mode is disabled and you drop a `BDB' table that is
      referenced in another transaction, you may get error messages of
      the following form in your MySQL error log:
 
           001119 23:43:56  bdb:  Missing log fileid entry
           001119 23:43:56  bdb:  txn_abort: Log undo failed for LSN:
                                  1 3644744: Invalid
 
      This is not fatal, but until the problem is fixed, we recommend
      that you not drop `BDB' tables except while autocommit mode is
      enabled.  (The fix is not trivial.)
