UDLD Loop on Carrier Handoff?

Hey Everyone -

Have an odd issue, and wanted to see if the hivemind had any ideas.

Have a point-to-point circuit with a regional fiber carrier that connects from their Juniper CPE to our Cisco Nexus edge devices on both ends.

The problem we're having is that on one end of the circuit, everytime there is a Carrier outage, the Cisco edge device puts the port into a udld Loop state, and effectively blocks the port. It stays in this state until the interface is flapped.

This is pretty inconvenient, as it prolongs outages. A brief 30 second outage on the carrier side might take an hour to fix, because someone has to log into the site/switch, and flap the interface.

Is there anything that can be done on the carrier CPE or our edge device to prevent this?

Also - any common causes for the udld Loop state on a circuit handoff interface?
