I have a couple of systems running 2009.06 that hang on relatively large

running against the same data doesn't hang on 2008.05.
There are maybe 100 snapshots, 200GB of data total. Just trying to send
to a blank external USB drive in one case, and in the other, I'm restoring
from a USB drive to a local drive, but the behavior is the same.
I see that others have had a similar problem, but there doesn't seem to be
any answers -

I'd like to stick with a "released" version of OpenSolaris, so I'm hoping
that the answer isn't to switch to the dev repository and pull down b134.
I still have this problem (I was msg34493 there).
My original plan was to wait for the Spring release, to get me to a stable
release on more recent code. I'm still following that plan, i.e. haven't
done anything else yet. At the time the "March" release was expected to
actually appear by April.
Other than trying more recent code, I don't recall any useful ideas coming
through the list.
It seems like the thing people recommend as the backup scheme for ZFS
simply doesn't work yet.
It has been working for a long time.
All of the lock-up issues I had were fixed in Solaris 10 update 8.
