if you just want to know why your program can't allocate more memory at 3Gb, one helpful pointer might be your ulimit manpage. Also: 3Gb may be your system's limit for any single process (especially if you're running 32 bit systems).
edit: just to be clear; I've run multi-threaded perl processes at 12+ Gb without any problems on 64-bit linux systems.
