Top, after killing off some processes:

Mem: 1204M Active, 424M Inact, 1072K Laundry, 219M Wired, 85M Buf, 1542M Free

It looks like what is happening is that many rsync daemon processes are bing created and do not die. I just checked and there were 49 running and nearly no free memory (17M). after a killall rysnc the free memory jumped to 1542M and left 9 processes still running for several minutes. By the time those died, memory was up to 2300M free. So it appears the issue is less swap and more rsync spawning many processes for some reason.

# rsyncd.log

# Set this if you want to stop rsync daemon with rc.d scripts
pid file = /var/run/rsyncd.pid

uid = root
gid = wheel

        path = /
        auth users = root
        secrets file = /usr/local/etc/rsyncd.secrets
