What is the minimal memory requirement for HAMMER?

[Zenny <garbytrash@xxxxxxxxx>]

Hi:

I am trying to experiment with HAMMER with a spare PIII/500Mhz old
machine with 256MB of RAM. I installed the RELEASE-2.10 version of
DFBSD.  But when I try to execute "hammer cleanup", it spits out an
error that reads:

"hammer: System has insufficient buffers to rebalance the tree.  nbuf < 3969"

However, when I checked in the archive of the mailinglist
(http://leaf.dragonflybsd.org/mailarchive/users/2010-03/msg00057.html),
it states that 128MB is the minimal requirement, right?!

In that case the hw that I am using exceeds the minimal requirement
and still spits out the error, which reportedly due to the low memory
(http://leaf.dragonflybsd.org/mailarchive/users/2011-05/msg00074.html)

Please throw some light! (Very dark here in Scandinavia during winters
like this) ;-)
