OK, I upped the large_pool to 3M. I recycled the instance and we are not using MTS or anything else that should be using the large_pool. No one else was on the system. I can't imagine a reason that a 1M segment wouldn't be available. Still got the same error. Any other ideas?
Try with lower filesperset value in the RMAN "backup" command.
