Re: Really OLD ISD/ISM/frm files

It turns out that the problem is actually related to the key size of the ISAM table. The key length was over the default buffer length:

[root@ irc]# ../isamchk -r mydata.ISM
max_key_length = 392, max = 279
../isamchk: error: 138 when opening ISAM-table 'mydata.ISM'

A recompiled version of 3.23.49 with the key buffer size changed was able to open the files and convert them to MyISAM.
