How do you conclude that NFD drops the Interest?

I can see from log that NFD delivers both Interests to the producer, but producer answers the second Interest with exactly same Data (the code might intend to increment m_counter but didn't do that), so that the second Interest can't be satisfied.

I was under the impression that producer doesn't print out the retransmitted Interest. Seems to work ok now. We can close this issue.
