Routing loop? Can you post your bgp config? Also, can you post the routes to the two addresses you peer with?

We have a J2320-JH, it has a Link to AS1200 over a 2meg serial x.21 connection and then a 100meg connection to AS1299 over ethernet. I have bgp from our as accepting ANY from them and announcing a single /23 network to them. My original 2meg connection has been stable and running a BGP session with no flapping for almost 3 weeks now. As soon as I introduce the new peer, the route table increases as you'd expect to around 500k routes, becomes stable with 245k active routes and then the originally stable connection starts to flap giving a Hold Timer Expired Error. This then keeps flapping. Whilst this first session is flapping there are no errors on the interfaces to either AS1200 or AS1299. However, whilst the session is flapping I note that almost exactly 1mbits/sec is going out of our new AS1299 connection and comming into our AS1200 connection. This traffic however does not come onto our LAN as the gig connection to our switch is showing none or very minimal traffic. The guys at AS1200 havent got back to me yet, but the guys from AS1299 have told me to check my prefix-limit, but I dont currently have this configured. JTAC tell me my router is fine and my configuration is correct. Anyone have an idea? The providers seem to be stumped but this leaves me with one peer disabled currently.
