I have an Ettus E310 from which I send some data via ZMQ to a computer.
On the remote computer I am running a Qt GUI in which I am displaying a FFT and a variable.
After about an hour, the GUI needs a restart because it blocks (sometimes the FFT freezes and sometimes the variable does not update). Why?
To update the variable I am using a thread in which a
variable_function_probe is used.
What is more, the memory and the cpu are not used in excess.
