[c-nsp] Weird config changes on C2621XM with AIM-VPN/BPII

[Patrick M. Hausen]

Hi, all

we monitor all our Cisco gear with Rancid and archive configs in CVS.
(http://www.shrubbery.net/rancid/)

One chassis shows a change of config once a day, every day. Five
minutes later at the next rancid run the change is reverted.

Any idea why the VPN AIS seems to go out have a beer precisely
once a day? It's not in use, currently. But this is annoying to say the
least and litters our CVS repository.

Thanks
Patrick
