Cisco VPN 3000 - Mismatched Proposal

[royalmail]

Just to give some background, we have been running a lot of global tunnels between Pix 506Es and a handful of VPN Concentrator 3000s for over a year now.

We recently bought another Concentrator, and rebuilt a bunch of tunnels from that hub site into about 7 other sites. We basically moved the tunnels from the Pix to the Concentrator. There are now about 7 tunnels going from out concentrator to other Pix 506Es and one other Concentrator. Anyway, I set the Concentrator to mail me with error messages. All tunnels seem to work fine, but I get the following error messages from a number of different tunnels every day. What do they mean and how can I clear the issue?

Many thanks for any assistance.

If no one has seen this error before, could you maybe point me in the direction of some decent resource so that I can chase it further please. I have alredy tried the in-house experts and their answer was basically, 'dunno, sorry.'. Also, the documentation that comes with the unit really is the bare minimum...
