Hi Jorge,
if I'm not mistaken, this is still your B200, so this might be funky stuff happening on USB3.
Important here is that you use the latest UHD; which version do you run (first line of output of uhd_find_devices)?
Best regards,
Marcus

Does anybody know where this error could come from?My python program just writes some samples in a file, reconfigure the central frequency and write again in a file with different name. Here is the related code:
for num in range(1,24): #to iterate between 1 to 24
tb.samp_rate = samp_rate = 2000000
tb.fft_points = fft_points = 1024
tb.frame_rate = frame_rate = int (samp_rate/fft_points/1000)
center_freq = 914e6 + (num*2000000) # Center freq modification
tb.set_center_freq(center_freq)
tb.disconnect((tb.logpwrfft_x_0, 0), (tb.blocks_file_sink_0, 0))
tb.blocks_file_sink_0 = blocks.file_sink(gr.sizeof_float*fft_points, '/home//FILE_SINK/'+ '914_+_' + str(num+num), False)
tb.connect((tb.logpwrfft_x_0, 0), (tb.blocks_file_sink_0, 0))
tb.start()
while(tb.blocks_file_sink_0.nitems_read(0) <3): #3 arrays of 1024
pass
tb.stop()
tb.wait()
