[FFmpeg-user] Trouble with encodnig UDP->RTMP

[Remo Rayamajhi]

Hello support ,
 I have a server from where i have to stream about 10-15 UDP stream to rtmp
, each time i run the ffmpeg script in bundle only 5-6 channels runs where
rest of the channels  doesnt work out .
But if i run the script of each channel separtely all the 10-15 stream
works . what is the main cause and what makes the streaming UDP to RTMP
fails
