They come because the packets for one EAP session are arriving from two different upstream home servers.
i.e. packet 1 comes from upstream A, and packet 2 comes from upstream B.
This usually indicates that the upstreams are broken, and failover over in stupid ways. Or, a server C is doing load-balancing across upstream server A and B, but isn't paying attention to the EAP state.
They SHOULD be load-balancing based on something common to all of the EAP packets, like Calling-Station-ID.
Or... maybe there are networking issues between your server and upstream server C. So server C thinks your site is down, and tries to fail-over to another path.

Running in debug mode shouldn't change the behaviour of the upstream servers.
