[Openswan Users] VPN works but getting errors

[Jeremy Schaeffer]

I have a functioning VPN connection between my centos box and a router 
with a dynamic connection. The VPN works, but I keep getting this 
message in the log files constantly -

May  2 08:19:22 services pluto[23699]: "VOIP-VPN"[4] x.x.x.x #325300: 
ignoring informational payload, type NO_PROPOSAL_CHOSEN msgid=00000000
May  2 08:19:22 services pluto[23699]: "VOIP-VPN"[4] x.x.x.x #325300: 
received and ignored informational message

What causes it? It is something to worry about and can I shut it off? -
