Bug #50564 Repair Table taking too long

Description:
I have a table 3.6GB with 4,14,000 rows, Index in three fields,

Accidentally ran repair table command on the table, it is taking too long to repair (waited for 13 hours), and if I restart my system it shows that table as crashed while repair,

How to recover the table?

How to repeat:
repair table 'table name'

Repair Table taking too long

you can't kill a repair without corrupting the indexes.  try this in my.cnf
myisam_max_sort_file_size=900G to make it faster.

what does processlist say, 'repair by sort' or 'repair with keycache' ?
BTW, 5.0.22 is too old to use, and you should be using 5.0.89 or 5.1.42 these days.

It says,

repair by sort

Please, send your entire my.cnf file content.

We finally discovered that the free disc space was too less. we got that increased and repair was done in less than 6 mnutes.

I would be greatful if someone can help us in optimizing my.cnf file for handling the load properly.

Thanks

So, the problem was NOT a result of any bug in MySQL code.
