A packet dump reveals that the TCP sender (FTP server) will send a

the
MX80 as an MPLS packet.
Hi Leigh,
you might be hitting PR736749:
In L3VPN scenario, transit packets which require fragmentation, traversing over
the
mpls core, might get dropped at the egress PE, if the egress PE?s, CE facing
interface
is on trio chipset cards. [PR736749: This issue has been resolved.]
It looks like that, but the packet was already fragmented and it was on ingress
of a PE ;-)
That description is not very precise. It affects also transiting
fragments. I'm sure you're hitting this bug.
Which JunOS Version are you using?
10.4R1.5
