I know that, the key word there is continuous space. In either case,
I'm only repeating what was said to me as the reason for purchasing a
brand new server - run in 64-bit mode to give Matlab more virtual
memory. It may end up being the case that the problem was completely
unrelated. I'll know in about an hour :)
