From the prompts and the addresses we can tell that the error messages came from the 2 EIGRP neighbors. We can not tell whether they came from the same time (and the clocks are just seriously out of sync) or whether they came from different times. Perhaps you can clarify.
One thing I would look at is whether there is much packet loss over this link. Use extended ping from one interface to the other, send 2000 pings and see if there are packet drops.
I am wondering if there might be a duplex mismatch between the 2 interfaces. Perhaps you can post the configuration of both interfaces and of router eigrp on both boxes.
If these are the only two neighbors on this link, this is a rather odd set of output messages.... When log-neighbor-changes prints out "peer restarted," that means the other router has transmitted an empty update with the init bit set. That generally means the other side thinks the neighbor relationship has gone down, come back up, and has received a hello from the local router, all within the dead interval. In other words, one side thinks the adjacency has reset, while the other thinks it's fine.
The only conclusion I can come to, I think (?), is that these two outputs are so distant in time that we don't see the other side at the same time. What you really need to do is--when you see this message on one side, pop over to the other router quickly, and grab the log from that side. If you don't have the log being saved, then telnet to both sides at the same time, and watch both for a while.
The reason is actually pretty critical to figuring out what the next step is. Is it the dead timer expired? Is it a retansmission timeout? Or is it an SIA? Each of these require different sorts of troubleshooting.
