mmap() fails

[Leonardo Giordani]

Hi all, I tried to use mmap() on a 4GB machine: this is the top output before 
running the test program:
 
Mem:  4011224K av, 1211456K used, 2799768K free,       0K shrd,  137580K buff
 
but if I try to allocate 2200000K bytes mmap() returns with 
ENOMEM...
 
Why does this happens?

Thank you

Leonardo Giordani
