#330 tcp write failed - error code / error reason not shown

[j0ka]

When I call iperf with the following command:

"iperf-2.2.n-win64.exe" -c ###.###.###.### -p 4711

I get the following output:

Client connecting to ###.###.###.###, TCP port 4711
TCP window size: 64.0 KByte (default)
------------------------------------------------------------
[  1] local ###.###.###.### port 49854 connected with ###.###.###.### port 4711
[  1] tcp write failed
[ ID] Interval       Transfer     Bandwidth
[  1] 0.00-6.20 sec  11.7 GBytes  16.2 Gbits/sec

First, iperf should print some more information on the reason for the "tcp write failed" error (error number, error description, ...).

Second, it seems that iperf ignores that error and continues, which results in the output of ridiculous high transfer rates (which are far beyond the physical possibilities of my system).
