Hi scotty.  I had a similar problem with a server.   Incremental backup
was very slow because is was comparing.  Then I made a full Backup which
worked well.  Next scheduled backup was successfull.

Try that.

We had similar problems recently when a network switch was
accidentally rebooted - several Solaris servers disagreed with the
switch about whether the link was full or half duplex.  The dropped
connections were fairly regularly spaced, as your's appear to be.  The
problems stopped after the switch and servers were forced to
re-negotiate (or the port settings were fixed on the switch).

We still get one or two ANR0480Ws per day, but those are user induced.
