Barney,
 
   A heavily loaded filer host may be to blame here.

   If this is something that just started happening, I suggest you
check the system load on the filer.  NetApp and Legato probably
suggest you switch to the NDMP client.  Anyway, similar 
failures happened to me when space usage on the filer crossed
some unknown threshold, causing the filer CPU to run busier
than it had before.  Apparently, the increased load slowed backup
operations so much that timeouts and other errors would occur
regularly.  For about 6 months, NetApp backups were spotty.
Now, after some clean-up, NetApp backups run fine again.

Terry
