Flapping POS Interface on Frame-relay between a Juniper and Cisco

Am having a problem that is buffling.

I recently changed a POS link encapsulation from PPP to Frame-relay.
Since that time the POS interface keeps resetting from time to time.

On my BGP session am receiving cease notifications from my upstream

The setup is such that we have a cisco on one end and a Juniper on the

interface POS0/0/0
 mtu 4474
 no ip address
 no ip unreachables
 encapsulation frame-relay
 logging event link-status
 crc 32
 pos scramble-atm
 frame-relay lmi-type ansi

ROUTERshow run int pos0/0/0.101
Building configuration...

interface POS0/0/0.101 point-to-point
ip address X.X.X.X
frame-relay interface-dlci 101

Any assistance on this will be greatly appreciated.
