This error is related to EIGRP resetting it's neighbor relationship, and indicates that the other neighbor initiates the reset of the neighbor relationship. The router getting the message is not the one resetting the neighbor.

Whenever EIGRP resets its neighbor relationship, it is noted in the log with the reason for the reset. In the earlier Cisco IOS Software releases, configuration to enable this feature is required. The command eigrp log-neighbor-change is configured under router EIGRP. In Cisco IOS Software Release 12.1.3 and later, the eigrp log-neighbor-change command becomes the default setting for the router. An example of the EIGRP neighbor log looks something like this:

No action is required on the router that is getting the message. Gather EIGRP neighbor log information on the other neighbor.

Can you share the neighbor logs? and also the configuration of the associated tunnel interface?
