[Discuss-gnuradio] UHD: Control Packet Attempt, Sequence

I am getting the following error when running my script - 

UHD Error:

     Control packet attempt 0, sequence number 391:

     RuntimeError: no control response, possible packet loss

Mostly "attempt 0", but one "attempt 1", six different sequence numbers.

Does this mean anything? Is my data good? Is there a way to write my script so I do not get this type of problem?

Thank you.
