Hello Ramesh,
I started to write to the SPOT developers, but you haven't given us enough context.
I see a rollback, requested by user, and not authorized for images. If that makes sense
to you (I admit I have no AWS install experience) good, or else you probably ought to
contact our Tech Support team to investigate/assist at a deeper level.
