Random deleteStream, client: 127.0.0.1, server: 0.0.0.0:1935 and signal 17 (SIGCHLD) received

[OnkelTem]

Hi!

I experience random stream resets.
This is my nginx.conf:

user www-data;
worker_processes 1;

pid /var/run/nginx.pid;
error_log /var/log/nginx/debug.log info;

events {
  worker_connections 1024;
}

rtmp {
  server {
    listen 1935;
    ping 20s;
    notify_method get;
    #chunk_size 4000;

    application full {
      # enable live streaming
      live on;
      allow publish 127.0.0.1;
      deny publish all;
      exec_pull ffmpeg -i rtsp://1.2.3.4:554 -c copy -f flv rtmp://localhost:1935/full/go;
    }
  }
}

When opening a page with player I get this in logs:

and video strarts playing OK. But then for no visible reason publishing stream just deleted, ffmpeg process is killed and restarted:

and again...
Any suggestions about these suicides?

I am also facing this problem. Did you find any solution? ffmpeg is getting killed without any reason in nginx logs.

[tgozed]

I used to have this issue. In the end I moved servers to a different hosting provider and that resolved the issue. I can only assume it was something to do with the firewall of my previous VPS provider.

I am also facing this problem...
Can someone help me with it ,please?

[misiek08]

I'm not sure, but I had similar problem and it was ffmpeg dying itself and causing nginx to reset it. So it was fully on ffmpeg side, randomly crashing after some long time.
