        This is disturbing, especially as I have not seen this
documented anywhere. I have a dual P-III 550 Intel system with 1 GB of
RAM (Intel L440GX+ motherboard). I am running Solaris 10U4 and am
using ZFS (mirrors and stripes only, no RAIDz). While this is 'only' a
home server, I still cannot afford to lose over 500 GB of data. If ZFS
isn't supported under 32 bit systems then I need to start migrating to
UFS/SLVM as soon as I can. I specifically went with 10U4 so that I
would have a stable, supportable environment.

        Under what conditions are the 32 bit / 64 bit problems likely
to occur ? I have been running this system for 6 months (a migration
from OpenSuSE 10.1) without any issues. The NFS server performance is
at least an order of magnitude better than the SuSE server was.
