I'll try and catch up with all the questions/points.
First up, I haven't personally seen the errors you have got. Others suggestions of an osga file that exceeds the 2GB limit is possible. This is not main memory limit but filesystem, or more specifically the C++ standard libraries suppport for file sizes greater than 2GB. Others have tried to increase this but I don't know of any successful workarounds for this.
If Linux is an option then you'll be able to get things working here much easier.

Hello,
32-bit windows has a 2GB RAM limit per program. OSG must be loading the
whole osga file. You can increase the RAM limit to 3GB. See this:

Note 32-bit OS's can access 2^32=4GB - (whatever the OS needs). Either do
the 3GB fix, cut down your file size, or upgrade to a 64-bit processor and
OS.

Just to confirm Jason's statement, I've run into the same error with osga >
2 gig as well.
So, Jason, how do you specify the directory for paging when you don't
archive the .ive files? I haven't done that before so just curious.
Thanks,
Brad
