Re: Hanging on copying to tmp table

The use of a specific index slows everything down, I have disabled that feature again, but as I wrote before, I cannot recreate the issue, as I do not know how it occurs.

Could there be something wrong with my settings, or is it recommened to upgrade MySQL ?

There is quite a lot of slow queries:
