Long running rinaperf test fails

[fdgonthier]

I've tested rinaperf with a very long duration and it failed this way:

Starting unidirectional throughput test; message size: 1451, number of messages: inf, duration: 1000000000 secs
write(buf): Cannot send after transport endpoint shutdown
write(stop): Bad file descriptor

In the kernel log, I get the following message:

Dec 20 22:59:15 edfserver9 kernel: [875035.384497] rina-dtp(ERR): Duplicate PDU or flow control overrun.SN:
