Solved: EIGRP continually flapping - Page 3

This is the message that I am getting from my 1941w router. I have a isakmp tunnel built with a GRE tunnel going through it. I keep getting the following message, continously.

The other end of the device is a 2801 router and it doesnt show anything in the logs. Anyone have any ideas? Thanks.
