Comment 17 for bug 1279699

Can be triggered when running 'iperf -c xxx.xxx.xxx.xxx' on this server and 'iperf -s' on another server.
Does not happen when running 'iperf -s' running on this server and 'iperf -c xxx.xxx.xxx.xxx' on another server.

In some occasions another error is kicking in too (Bad DLLP):
