Brain server can't write above 4GB

[illyria]

Did a little digging, and I may be way off base - seeing as I don't really code much, and have never done anything in C/C++

But this thread on MSDN suggests that on Windows fwrite cannot write out more than 4GB - MSDN - and if attempted exhibits exactly the behaviour I (we) are seeing here.

So no matter what the size is if it's above 4GB (i've tried to write 10GB originally) it writes out whatever is above closest multiple of 4GB (in the case of 10GB - it writes what is above 8GB hence 2GB) then it gets count as something in multiple of 4GB units (say 8GB) and does

nbytes = (unsigned)(8*1024*1024*1024) =0

and tight loop forever.
