swap, but
apache runs out of memory waaaay before then (maybe 500MB) even though 
reports 1400M Free.

I've tried setting datasize to 'infinity' using `limits`, but that 
didn't stick
(I ran it again, and it still said datasize was limited to 524288).  I 
tried to adjust kern.ipc.shmmax to 6GB using `sysctl`, but it didn't 
make a
difference.  FYI, that variable's upper limit is 2147483647.

What can I do to give apache2 access to all the addressable memory on 
Do we have PAE? If not, can a 32 bit processor even use 2+4GB? I recall 
that some year(s) ago, people were adviced not to use more than 4GB 
totall memory on FreeBSD. Could be wrong, though.
