I have a frame-relay T1 with multiple point-to-multipoint subinterfaces sharing it. I want to limit the amount of bandwidth each PVC uses. I have some simple Traffic-shaping parameters set, but I still see BECNs and dropped packets. Are there other things I should be looking at to limit its use.

Peter,
what type of traffic are you running over these PVCs.
Is it voice, voice and data or just data ?
There are different parameters that you should set for traffic shaping, if you are running voice/data.
What is your CIR for these pvcs ? Does the configured CIRs conform to what you have purchased ?? Post in your configs, for further analysis.

This is only for data, no voice.
Most PVCs have a PORT and CIR of the same speed.
Regarding your question " Does the configured CIRs conform to what you have purchased ??". Do you mean what I have configured? If so, the answer is yes.
On the central router, I have the following configuration:
interface Serial1/1
mtu 8192
no ip address
no ip directed-broadcast
encapsulation frame-relay
no ip mroute-cache
frame-relay traffic-shaping
frame-relay lmi-type ansi
!
interface Serial1/1.806 multipoint
ip address 172.25.249.57 255.255.255.252
ip nat inside
ip ospf network point-to-multipoint
no ip mroute-cache
bandwidth 512
frame-relay class CIR-512k
frame-relay map llc2 806
frame-relay map ip 172.25.249.58 806 broadcast
frame-relay interface-dlci 806
!
map-class frame-relay CIR-512k
frame-relay cir 512000
frame-relay bc 64000
frame-relay mincir 512000
