Thanks for your feedback..
So if i set my VM to 8 GB, each proccess would use a max of 3 GB (even with PAE installed and selected on boot)?

Yes, using a PAE enabled kernel. Anyway, apps won't be able to use more
than 3GB per process. Welcome in 32 bits limitations.

Strange. 64 bits is here for years, 64 runs 32 bits code perfectly.

Either PAE or switch to 64 bits. There's no other path.
