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.
