Your question is vague.
Sorry, it was not intentional. I wasn't too sure how to ask the question.
A 32-bit process can only access 4 GB of memory, but all processes also
have a bit of memory "reserved" for the kernel. On FreeBSD the
accessible memory for processes is closer to 3 GB than 2 or 4. See this
discussion for details: http://wiki.freebsd.org/KVA_PAGES
Also, FreeBSD processes have administrative limits to their size set by
defaults. See for example this:
http://unix.derkeiler.com/Mailing-Lists/FreeBSD/questions/2008-11/msg01363.html
. If you want to use the whole 3 GB for a process, you'll have to
increase maxdsiz. Note that you may need to experiment with this size
since your BIOS will probably not let you use 4 GB of physical memory
for the OS except if you enable PAE, and it's possible to create an
unbootable system by messing with kernel memory limits. You should
probably experiment on the loader command line first, not in the
loader.conf file.
Thank you. This is exactly what I was hoping to learn. Thanks also for the links for further reading.
