Thank you. Sorry for this kind of silly question I just didn't want to
believe that each apache process was using 42 MB of physical memory
and 322 MB of virtual memory :-)
I guess the total memory used by apache is not 42 MB*the number of
processes, but less than this as there is some overlap (for shared
libraries, etc)
