Certain things, like the query cache, index cache, etc. are allocated once, at startup. Those are fixed memory requirements. Other things, like read buffers, sort buffers and the like get allocated every time a client connects. Those are dynamic memory requirements, and the amount they use increases linearly with the number of concurrent connections you get. Thus, increasing the max connections can never *reduce* your memory requirements - only potentially allow *more* memory to be allocated. I still suspect that you ran out of memory because you had a sudden influx of connections; and now that you've increased the max connections you'll run out of memory even faster next time that occurs. If it works now, it works; but keep that in the back of your mind somewhere for next time you see it occur :-) -- Bier met grenadyn Is als mosterd by den wyn Sy die't drinkt, is eene kwezel Hy die't drinkt, is ras een ezel Get your world in your inbox!
