[c-nsp] IPv6 BGP on 7200

[Stefan M. Brandl]

Hi,
I have two Cisco 7206-NPE-G1, connected via OC3.
Both routers do BGP with IPv4 and v6.
The v6-session goes down every 10-30 minutes:

Feb 27 08:08:18: %BGP-5-ADJCHANGE: neighbor 2001:16E0:0:5:0:DEAD:BEEF:1 Up 
Feb 27 08:15:54: %BGP-5-ADJCHANGE: neighbor 2001:16E0:0:5:0:DEAD:BEEF:1 Down Peer closed the session
Feb 27 08:16:24: %BGP-5-ADJCHANGE: neighbor 2001:16E0:0:5:0:DEAD:BEEF:1 Up 
Feb 27 08:57:25: %BGP-5-ADJCHANGE: neighbor 2001:16E0:0:5:0:DEAD:BEEF:1 Down Peer closed the session
Feb 27 08:57:58: %BGP-5-ADJCHANGE: neighbor 2001:16E0:0:5:0:DEAD:BEEF:1 Up 
Feb 27 09:10:17: %BGP-5-ADJCHANGE: neighbor 2001:16E0:0:5:0:DEAD:BEEF:1 Down Peer closed the session
Feb 27 09:10:45: %BGP-5-ADJCHANGE: neighbor 2001:16E0:0:5:0:DEAD:BEEF:1 Up 
Feb 27 09:17:46: %BGP-5-ADJCHANGE: neighbor 2001:16E0:0:5:0:DEAD:BEEF:1 Down Peer closed the session
Feb 27 09:18:18: %BGP-5-ADJCHANGE: neighbor 2001:16E0:0:5:0:DEAD:BEEF:1 Up 


The IPv4-BGP-session is stable.
Both routers also do v4 and v6 BGP to other routers just fine.
Where could be the problem? How to debug?
