FFMPEG transcoding gone down after few Minutes.

[drpaudel]

I am transcoding udp source to rtmp output.

ffmpeg -timeout 2000 -y -i 'udp://@239.1.3.105:8002?fifo_size=1000000\&overrun_nonfatal' -f +global_header -c:a aac -strict experimental -b:a 64000 -ar 44100 -ac 2 -ab 128k -s 640x360 -vcodec libx264 -pix_fmt yueset:v faster -r 30  -f  flv 'rtmp://admin:admin@192.168.2.200:1935/live/wtvZEEANMOLCINEMA.stream'

After Few minutes it starts giving error like

And stream stops transcoding. I could not find the issue. I would appreciate if some one help me to solve this problem.
I have attached all source script and ffmpeg log.
