As a rule, we don't rule these things out that easily.  I would properly
investigate the network layer, just in case.  CIFS is unique in the way
it holds open long sessions which can be rather sensitive to
disconnection (with subsequent failures in oplock breaks, and other
things).

As to this particular error, if the client isn't complaining, it may
just mean that the client disconnected from the server, in an abrupt
manner.  The new 'timing' basis might be due to something now touching
the connections every 30 mins.  I'm a bit more worried however, because
of the 'breaks on access' part - it smells like the kind of issue that
bad network hardware brings up.
