Has anyone ran across this error on their Prodigy instruments?

I've had several people say they ran long carbons last night and had little
to no signal. There did appear to be more Receiver Overflow errors than usual.

The probe is still cold and a quick 16 scan carbon this morning shows strong
signal.

E2321: Rapid Buffer Vacuum Decay. Pumping Non-Stop.

On a related note: We have had issues cooling down after refills for the last
several months. Tightening the screws at the Fill and Exhaust ports on the
Prodigy Dewar neck seemed to help, but the last time took almost two hours
to go back to cool. Bruker suggests a leak, but I'm not sure where it is.
