Question

Node Server Killed while transferring file bigger that 60 MB

I am using a Droplet with 1GB RAM and 1vCPU configuration to upload files from nodejs server.

Whenever I try to upload file bigger than 60MB node server gets killed.

My Nginx Default file config.

                proxy_pass http://localhost:8081;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto $scheme;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection 'upgrade';
                proxy_cache_bypass $http_upgrade;
                proxy_max_temp_file_size 0;
                proxy_connect_timeout 1800s;
                proxy_send_timeout 1800s;
                proxy_read_timeout 1800s;
                proxy_buffer_size 128k;
                proxy_buffers 128 256k;
                proxy_busy_buffers_size 256k;
                proxy_redirect off;
                proxy_request_buffering off;
                proxy_buffering off;

My nginx.conf file

        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 1800;
        types_hash_max_size 2048;
        client_max_body_size 4096M;
        fastcgi_read_timeout 1800s;
        client_body_timeout 1800s;
        client_header_timeout 1800s;

I am trying to solve this issue for hours and stuck.

Hi there,

What is the exact error that you get when the Node.js service crashes? Also, do you see any errors in the Nginx error log too?

Also, you can try adding a swap file so that you could have some extra buffer in case that your server is running low on memory:
