I have 1.5GB or RAM, with PAE installed. With various kernel patches, no X, and some other constraints I can malloc up about 1.2GB before the system becomes unstable. In fact, I can just barely get about 1.6GB -- but that much will usually cause a system reset. My application requires about 1.5GB to run nicely. Can I get that much with FreeBSD? And to the people who have made FreeBSD possible, even taking the time to answer my (and others) questions, thank you! I just have one final thought: Bill Gates said we'd never need more than 640k. --jg
