  11 ...               Bgp implemented with singleton accepts only one incomming conection. Exabgp
  12 ...               logs will show that one peer will be connected and two will fail.
  13 ...               After killing karaf which owned connection new owner should be elected and
  14 ...               this new owner should accept incomming bgp connection.
