I was running OpenBSD 3.3-STABLE.

Yes, class.  My bad, just using the wrong term is all.

memory hog :)

Part of the problem might be that.  But I don't see any memory spike,
I don't really see any noticable increase in memory at all.  I can
believe that sa-learn is a pig, but on a machine like this, I shouldn't
get an "Out of memory" error unless I'm whacking a limit that I'm not
aware of.  And if running ELF increases the memory enough that an old
machine with 1/4th of the RAM can do it, while this one cannot... Well,
that doesn't quite add up to me.  :/

Incidentally, I'm running bash from packages, and 'ulimit -a' shows:

[benny@fusion ~]$ ulimit -a
core file size        (blocks, -c) unlimited
data seg size         (kbytes, -d) 1048576

max user processes            (-u) 532

I also switched to bourne shell, with the same result.  :/
