[Samba] Oplock break request failures

I hope someone can enlighten me on this.
Situation: NT network, Samba PDC, about 20 NT 4.0 workstations. log(s).smbd
are created per machine for easier analysis (as log.smbd.<NetBios Name>).
Not often, but often enough to be of concern, are errors in
request_oplock_break that seem to indicate that another smbd process that
should be listening for break requests on a UDP socket isn't, or isn't
responding. Some time ago, for some very strange reason, the system was
configured with share modes off, which caused these errors to occur
constantly. That was corrected and now they are infrequent, but not
infrequent enough, I suspect, to ignore.
One possibly significant fact: there are two subnets. The cross-subnet
browsing recommendations have been followed and we have no trouble browsing
across the subnets; but all of the failures I'm writing about occur on the
subnet which is remote from the one on which the Samba PDC resides. None of
the samba logs associated with any of the several NT workstations on the
local subnet with the Samba machine show this error. I can't see how that
would matter, given that the inter-process oplock break requests are simply
UDP communications and don't use subnet broadcasts - unless I'm mistaken, a
very real possibility. :-)
Does anyone have a hint on what might cause this, how to troubleshoot it more
fully, or if it's really nothing to worry about?
