Re: memory size limits in Linux version

Hi Rob -

I think the issue may be that there isn't enough swap space configured on your
Linux machine.   Our linux version of Ferret was actually built on a Linux machine
that only has 512Mbyte of RAM.  However, when I run Ferret, I can do a

and it works fine.  The reason for this is that, though we only have 512Mbyte of
RAM, we have our Linux system configured with 2Gbyte of virtual memory/swap space.

If you can add swap space to your Linux machine (fairly straightforward using the
"swapon" command, I believe), I think you'll find that you'll be able to set
higher memory limits.
