SmbClient Kills NT 4 in conjunction w/ Amanda (Revisited)

Ok.. I've tried tweaking several settings on Samba (1.9.18p4) in order to
try to keep it
from killing several machines that get backed up weekly via Amanda (using
smbclient).
What always appears to happen is that for one reason or another, Samba is
booking
along copying files and then all of a sudden NT stops communication and
smbclient ends
up hanging forever (regardless of the keepalive setting). Now, at this
point, the NT
client is completely DOA and IF you were to look at the network neighborhood
on that
machine (assumed you were still logged in), you would see ONLY that machine!
Now, I've heard from other users (at least one) that this has been seen at
other
establishments and I believe on other platforms (non Solaris).. I would like
to find a fix
for this, and I don't need someone bitching at me claiming it is a problem
with NT (Yes,
I did have someone e-mail me saying that). The bottom line is that this IS
a problem,
and somehow I would like to solve it. Now, we have two machines that
exhibit the
problem and both are running NT 4 SP3 (I believe the other is running SP3).
I currently
do NOT have a complete log of the activities of one of these sessions, but
will attach
one at the next failure.
We are currently doing full disk backups (less any of the standard locked NT
O.S. files)
for 8 machines and typically it kills one or more of the machines each week
(my machine
is usually the first to go). I'm upgrading Samba to 1.9.18p7 tomorrow
morning in the
vain hope that my problems may be reduced, but am reluctant to make any
assumptions
yet.
