1. you can parallelize or limit it on the backup
2. You can virtual restore your backup just taken to validate everything is
3. You can direct rman to use the Large pool 
We have used it on hoards of databases and have not had a problem.
Pinning the rman packages is the latest thing I saw help.
Oh... if you do it to tape... I found it's lots of fun but doing it to disk
gives us 99.999 percent success.

        what version of oracle?
        you can limit the resources used by rman to some extent in 9i but
        gives you more options. 
        i don't think there is an answer for the question you are asking.
