SonicWall VPN Warning Message. What is causing it?

About 6 or 8 weeks ago I started seeing this warning message in my SonicWall logs...

07/14/2009 08:56:18.192 - Info - VPN IKE -       IKE Initiator: Start Quick Mode (Phase 2). -       66.17.22.101, 500 -       209.52.125.77, 500 -       VPN Policy: Candraft - Coquitiam
07/14/2009 08:56:18.240 - Warning - VPN IKE -       Received notify. NO_PROPOSAL_CHOSEN -       209.52.125.77, 500 -       66.17.22.101, 500 -

IThe message is repeated over and over. The VPN tunnel is up and working normally. IP 209.52.125.77 is the other end. I've emailed the admin there and he says nothing has been changed on his end and all is working OK. Nothing has been changed on my end either. Just what is this message telling me and why?

Thanks,
Rick

Above logs indicates the policy Candraft - Coquitiam which is in use; Quick mode refers to Phase 2 of VPN negotiations; this message means that phase 2 is negotiations are started [may be due to max data or time as per configured values]. This is an info message and is normal.

Above messages indicates that while negotiations were going on, no matching proposal was found between the ends; this is not an error but a warning which possibly indicates some misconfiguration.

As the tunnel is up and there is no disruption of service these messages can be treated as harmless.

I would suggest you to double check all the settings at both ends; also check with ISPs if they have modified anything on their network which might haev resulted in these messages [simple things like switch/router firmware, etc.]

Thank you.
