IIRC the limit is 3GB on Linux. Ah, then it was probably this limit. 32-bit Linux, that is. Get an Opteron/Athlon 64 or other 64-bit processor and you don't have this kind of a limit (it's much, much higther). > Of course there's also a physical limit and you would need a 64bit CPU > in order to use more than 4GB. There's PAE36 or High memory[1]. You only need a kernel compiled with 4GB or 64GB support (the machine was Xeon with 6 GB). That has nothing to do with process size limit. -- Robert Krawitz <rlk@xxxxxxxxxxxx> Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail lpf@xxxxxxxxxxxx Project lead for Gimp Print -- http://gimp-print.sourceforge.net "Linux doesn't dictate how I work, I dictate how Linux works." --Eric Crampton
