Hi guys

I wrote some code . and ran those with launch file . every worked thing fine at the first but after a few minutes I got this msg:

[QR_left-2] process has died [pid 9513, exit code -11, cmd /home/hamid/Working_space/Qr/bin/Qr_detection /QR_left/image:=image __name:=QR_left __log:=/home/hamid/.ros/log/f2d341cc-05c7-11e4-9fa2-002682d6e390/QR_left-2.log].
log file: /home/hamid/.ros/log/f2d341cc-05c7-11e4-9fa2-002682d6e390/QR_left-2*.log
