Genesis validator not starting validation

[acroca]

I'm running a private network locally and every now and then (no apparent reason) the genesis validator refuses to start validating. I attach the logs:

When I run eth in its console I get the following:

There's already another node in the same network before I trigger the genesis validation. Maybe this is the reason?
