That is incorrect. Recycle does not finish the tape when the Hold command is 
issued. Recycle finishes the dataset that is in progress and then comes to 
pre-mature end.
A Hold on Expirebv has the same effect.

I agree with "don't cancel" as many bad things can and do happen.

When you hold RECYCLE, it will finish the tape it is currently recycling, and if
I'm not wrong, it will finish the entire volume chain (if the volume was part of
a chain).  Try HOLD RECYCLE EOD instead as it will hold at the end of the
current dataset.

Audit is another long-running function that can also hold up CDS Backups.  I'm
not sure if HOLD AUDIT EOD helps, but I generally add EOD to everything just
to be sure.

Yes, CDS backups are the first thing AUTOBACKUP does...SSM does not kick
off any CDS bkups.
