Re: Win32 Backend Cash - pre-existing shared memory block is still in use

Thanks for the tips. I would move to LINUX if it was an option :(

I will bring the numbers down and do some benchmarking and tests to find out what I can get away with on this system.

Thanks again,
Jeremy

I would be WAY cheaper in time and effort, to just build a simple 64
bit linux box, toss 16 or 32 Gigs in it, and put your reporting db on
there.  Trying to do "big memory" things in windows is, at least for
now, a net loss.
