I was seeing similar problems on a dual quad core box that also was running the 
above as well as postgreSQL until I took the memory from 4 Gig up to 8 Gig of 
memory (the boxes were special priced with only 4 gig of memory is why I tried 
it that way). Since moving it up it has been stable as a rock (or rather as the 
Ubuntu box sitting next to it) and no longer runs out of memory. I was seeing 
even worse problems on Ubunutu X86_64 at 4 Gig of memory so it's not an freeBSD 
issue.

  4 Gig is a "Bad Thing" on Intel x86 motherboards because of all the cruft of 
the 386 address space layout.
