I can imagine some circumstances where you might use more RAM in the new loader
than in the older one. This has to do with large color palettes and external
reference palette overrides. Raise your notify level to PFNFY_DEBUG and verify
that you are not reloading the same external references more than once, unless
you intended it. To help you fully, I will ask you these questions for
starters:

What version of the OpenFlight loader are you using with 2.1?
What Flight or OpenFlight version is the database(s)?
Are you using external references? What version is the referencing file?
Are you using MIPS II binaries?
How much RAM does you machine have?
How much swap space does your machine have?
What are your shell "limit" values?

Use osview or gr_osview to verify your suspicion. If you are hitting swap
space then the short answer is to buy more RAM.

Regards.
