I donot think these messages are the actual error reason for the connection not getting completed.. these are just a bunch of informational messages. I would suggest turning up the logs on the concentrator side for IKE, IKEDBG, IPSEC, IPSECDBG, AUTH, AUTHDBG for Severity to Log 1-13 and see what the errors it shows. The Concentrator log is where we will get a resolution from.
I have not yet received any reply stateing exactly what the error message means however I did overcome my problem with regards to these messages. I found that the end user, who was generating these messages was using a UDP hub to his DSL connection. I had him remove the hub and use a regular Ethernet card and the problem was resolved. Hope this is of some help.
