Glad to hear that, but it seems unlikely, to me.
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 :-)
