memory limits

Hi there,

I'm running a very memory intensive php 5.0 script through apache2 on a recent 
DragonFly build (Sept 1).  My problem is that I'm running into some OS limit or 
something.  I'm assuming this because I have 2G physical RAM and 4G swap, but 
apache runs out of memory waaaay before then (maybe 500MB) even though top 
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 also 
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 this
