Running 12.2(15)T17 in a lab environment on a 2520. Half way through my lab exercise, this router suddenly has no EIGRP neighbors. The neighbors still think they have adjacencies. Then they start flapping too - not through dead-time, but because retry exceeded.
Looking back through the log, I find, just following a reload:

Has anyone any idea what that could be about? At the time, I was not touching anything to do with the EIGRP. The only thing that should have been going on was some IPv6 routes turning up through the OSPFv3.
