Hi,

I had simular error outputs from RMAN when NB encountered media write errors
(84).

Try to check NB Problem report during time when backup failed. 

I have experience thad here is a bad relation between NB and RMAN
interfaces. So I was not able to find theese type of errors in NB namy times
until I checked NB Problem Report (found 84 error). Now I am storing and
rotating RMAN logs in filesystem and after any RMAN job running grep to find
out if  error is there.

netbackup:

working until saturday...  no software changes have been made to the master
or client.
