Hi ,
ORDER BY, will always use some temporary table for doing sort operation.
For that matter, any group function, like min,max,group by,order by will use
temporary table before displaying the final results.

Also, its not good to set sort_buffer_size=256M, as this much of memory will
get allocated to each session, and if u have more than 10 connections at any
point of time then it will more than 2GB RAM will get allocated and system
will be slow.
I feel sort_buffer_size=1MB should be good in my.cnf
neither of those have fixed the issue.. I can create a sample database if
anyone wants it to be of some help.

It goes to a temporary table when MySQL does not have enough memory
(allocated) to store the temporary results in memory, so it needs to create
a temporary table on disk.
Try increasing the memory buffer size or eliminating more rows from the
query.
