Just recently got engaged with a customer who has a specific Oracle RMAN backup failing time & time again. It was observed that it ran fine for about 2 hours before it bombed.
Here is the error message.
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

VxBSASendData: Failed with error:

We are suspecting it to be a NIC issue (Probably NIC Hanging) and possibly trying to swap NIC’s around, if we have a spare one.
Workaround formulated is:
1. Swap the NIC with another to see if the problem moves.
2. Replace the card and see if we still have the problem.
Please advise...
