raspberry pi - Can this Python script cause an R Pi freeze? -


the python script below seems cause raspberry pi 3 freeze after few hours when running in background. might file operations in while loop cause memory leak?

i'm starting script via line below in /etc/rc.local

(sleep 10;nohup python3.4 -u /home/pi/soundserve.py /home/pi/soundserve.output.txt 2>&1) &

thanks in advance help!
