Windows imposes a 2GB limit on each 32-bit application, regardless of how much memory you actually have installed. Therefore, in order to use more than 2GB, you have two choices:
(1) Run the program on a non-Windows machine, such as a Mac or Linux.
(2) Compile Panda (and all of the needed thirdparty libraries) as a 64-bit library and use that. You will need to be fairly comfortable with compiler systems to do this successfully.
I’ve also heard rumors that you can configure Windows to allow slightly more than 2GB, though I don’t know the details there.
Your other choice is, of course, to bamify each of your egg files separately. This might be a more robust choice anyway.
