<Keepalives are temporarily in throttle due to closed TCP window>

Mon Sep 14 16:05:01 UTC 2009

I am having difficulty maintaining my BGP session from my 6509 with
Sup-7203bxls to a 7206 VXR NPE-400.  The session bounces every 3
minutes.  I do have other IBGP sessions that are established with no
problems, however, this is the only IBGP peer that is bouncing
regularly. 

cr1.AUSTTXEE#show ip bgp neighbors 67.214.64.100

<SNIP>

  BGP state = Established, up for 00:02:54

  Last read 00:00:53, last write 00:02:54, hold time is 180, keepalive
interval is 60 seconds

  Keepalives are temporarily in throttle due to closed TCP window

  Neighbor capabilities:

    Route refresh: advertised and received(new)

    Address family IPv4 Unicast: advertised and received

  Message statistics:

What does exactly the message mean and how do I stabilize this?  Any
help will be appreciated.
