Thanks for the hint! I sure was calling service.run twice... Nontheless I removed the call in the while loop, but I still get multiple messages written to the console. Is it possible that the service does not get stopped properly and its threads keep on running? If so, how can I securely delete my service object with all its threads? I thought I could use it the 'RAII' way... Sincerely Dieter On Sun, Nov 17, 2013 at 11:39 AM, Le Ba <hma...@gm...> wrote: > Excuse my poor English.
