Description

NFD on producer crashes when ethernet cable is unplugged and re-plugged. This behavior is consistent on UDP multicast face and inconsistent on UDP unicast face. Crash scenario was reproduced using a laptop as consumer and raspberry pi 3 as producer running ndnchunks application. Wire was disconnected and re-connected during data download. One example log is attached.

How are you creating the unicast face? Specifically, I want to know if it's on-demand, persistent, or permanent.

Unicast face is persistent. I used the default command:

nfdc face create udp://<ip_addr>

And you're running that command on the producer machine?

Both on producer and consumer. On consumer : <producer_ip_addr>, and on Producer: <consumer_ip_addr>.
