Hi Ian,
Thanks for the suggestion. I haven't got any such error in the backup log.
Only (unrelated) error I ever got was when I took the first backup on Feb
9, due to small setting for MAXSETSIZE which I fixed and took
subsequent successful backups (.... datafile or datafile copy larger than
MAXSETSIZE: file# 2 /u01/oradata/AIS/undotbs01.dbf...).

I am also using the controlfile and not rman catalog.

Even though I am not seeing exactly same symptoms as your case, your
suggestion sounds promising so I will try it and report back.

Thanks,
Paresh
