This is usually due to your network subsystem re-ordering packets, which is never supposed to happen but certain
 1GiGe interfaces, particularly USB ones, do this quite a bit.

Are you running inside a VM?

What kind of network interface do you have?

Hello,

        I'm working on developing some gnuradio exercises, some of which involve using USRP N210 devices as transmitters. When I attempt to run the related flowgraphs, I get a stream of sequence errors (S) in the GRC log window. Attached are a pair of GRC flowgraphs in which I am getting this error. I have tried installing the latest images to the USRPs and updating to the latest version of gnuradio available on the github master branch. Can somebody please point me to what I'm doing wrong? I've searched around on the topic for quite awhile, to no avail.

Thanks,
George
