The Spectrogram service was stopping after it completed it's work (no issue here) and the system would start it again 10 seconds later, sometimes it would stop and start multiple times a second (no file to analyse maybe) Added a while loop to that it would just keep running and sleeping for the number of seconds of the recording length setting.
