high cpu usage with no client connected Ubuntu server 16.04 #109

Closed iw5ejm closed 6 years ago

Is normal that the csdr process is running also with no client connected and using cpu as if there was clients? schermata 2018-02-08 alle 23 48 25

Could you please tell the full command with top -c? If it is csdr fft_cc, then it is okay.

This is normal. The csdr fft_cc process runs always, even if there is no user connected. This is which generates the waterfall diagram. It was easier to implement this way (although starting/stopping this process could be done).

iw5ejm commented 6 years ago

Ok so to try stopping the fft_cc process I have to look in csdr.py file, DSP class right?

ha7ilm commented 6 years ago

Yes.

You should look for spectrum thread.
