#64 Server not always sends the full displayed log to client

[Daniele]

Hi, I'm working on a solution to remote bi-directional TCP iperf tests on CPEs;
as I understood (please correct me if I'm wrong), the client can "download" the displayed results from the server. I noticed the displayed results server side and client downloaded results don't match.

On CPE client I send the following command:
iperf -c <server ip=""> -r -P 5</server>

On Server the command used is:
iperf -s

I expect to see on server display 2 messages logged as "[SUM]" (the sum of multiple streams),
one for UL and one for DL; on the CPE side, my custom Firmware parses these "[SUM]" tags to get the UL and DL info. I noticed sometimes I can find only 1 "[SUM]" raw in my downloaded display results; if you look at server side display, you can see 2 "[SUM]" raws.

Can someone help me in understanding how to solve this? It happens about in 30% of the tests.

In attachment what the server shows in the CLI, and what the client receives from the server.

Thank you,
Dan

Both client and server versions are 2.0.5 (pthread) running on Linux.
