It is not a nasty bug, but problem of inappropriately configured IP and MPLS MTUs on transit nodes.

9.3R4.4 has a nasty bug which occures in setup when you have bgp session over 
chain of few routers/links with ospf/ldp

bgp session occasionally goes down with notification timeout. Even when there is 
no traffic at all and no physical errors

rollback to 9.3r3 helps though


JTAC still not confirmed it, but it easlily can be reprodused in lab
