[c-nsp] Cisco 7206VXR (NPE-G2) SRD4

[Anrey Teslenko]

Hi all,

We recently has tried to update IOs version on our  Cisco router 7206VXR
(NPE-G2) up to SRD4 12.2 (33).
But we observed trouble with bgp process.
Some sessions had not risen or got down with following notifications

May 25 07:28:29 router.name.net 118: May 25 07:28:29: %BGP-5-ADJCHANGE:
neighbor  Down BGP Notification sent
May 25 07:28:29 router.name.net 119: May 25 07:28:29: %BGP-3-NOTIFICATION:
sent to neighbor <ip-address> 4/0 (hold time expired) 0 bytes
May 25 07:28:30 router.name.net 120: May 25 07:28:29:
%BGP_SESSION-5-ADJCHANGE: neighbor <ip-address> VPNv4 Unicast topology base
removed from session  BGP Notification sent
May 25 07:28:31 router.name.net May 25 07:29:38: %BGP_SESSION-5-ADJCHANGE:
neighbor <ip-address> VPNv4 Unicast topology base removed from session
 Unknown path error

The dampening was disabled and  some sessions were in a up status and not
got down.
So we have made rollback. But this is situation very unpleasant.

I have found nothing  on cisco.com

Please help me, if anyone had something similar.
