Thank you for the problem report. Please, send the results of SHOW TABLE STATUS for the table.

You have 230 or so partitions in MyISAM table... Please, check if the same problem happens with mysam_sort_buffer_size = 1M and sort_buffer_size = 1M.

Thank you, it does not happen now. Can you tell me how the buffer and size variables are used in memory consume for tuning my and other systems?

So this looks like a result of misconfiguration, not a bug.
