NFD

I by mistake started another instance of nfd on another terminal, which as expected quit after printing out the following messages:

---

However, after this I couldn't connect any producer to already running nfd. To connect any producer again I had to restart the running nfd as well.

Steps to reproduce the error:

On Terminal 1 start nfd:

$ sudo NFD=1 NRD=1 NFD_LOG=all ~/nfd/build/nfd --config /usr/local/etc/ndn/nfd.conf.sample

On Terminal 2 start another instance of nfd:

$ sudo NFD=1 NRD=1 NFD_LOG=all ~/nfd/build/nfd --config /usr/local/etc/ndn/nfd.conf.sample

(This will give the above mentioned errors and will quit)

Start producer:

$ NFD=1 ~/ndn-cpp-dev/build/examples/producer

ERROR: error while connecting to the forwarder (Connection refused)
