The obvious question would be whether you are using "Maximum Allocation" MAM
or "Russian Dolls" RDM model for your DS-TE.

My advice is don't do DiffServ Aware RSVP-TE. 
Use IntServ i.e. your standard core QOS instead and use RSVP-TE just for
traffic engineering purposes (pure RSVP-TE is complex enough).
