Hi Navdeep,

Could you also attach the corresponding NLSR log file? Thanks.

Hi Vince,

Thank you for your reply. I saw the NFD logs(attached) and could not find any point where NFD is failing. But surprisingly, I could see that there is less number of interests that are forwarded even in the case they are not satisfied with the cache. I am using NDN Traffic generator to create the traffic in the network. Any pointer would be helpful. I am using a simple topology:

Client1-->Client2-->Server (There are 3 paths from Client2 to server) Attached is the traffic generator client and server configuration. Please help.

Thanks and Regards,
Navdeep Uniyal

Hi Navdeep,

This error is usually caused by the NFD process on the node terminating; NLSR is unable to receive data from NFD’s Unix socket.

Can you check or share NFD’s log to see the reason for the process’ termination? It could be something wrong with the configuration or if you are using ctl^c to kill a process on the Mini-NDN command-line, this can sometimes kill NFD processes also.

Hi everyone,
