Socket timeout on large ingests

When i trying to ingest large tracks (30+ minutes length) it ingests very long:

debug: Ingested new track in 215262ms. track_id=116

After those ingests, no response returned to client. Added event listeners on created sockets:

server.on('connection', function(socket) {
    log.info('SOCKET OPENED' + JSON.stringify(socket.address()));
    socket.on('end', function() { 
      log.info('SOCKET END: other end of the socket sends a FIN packet');
    });

    socket.on('timeout', function() { 
      log.info('SOCKET TIMEOUT');
    });

    socket.on('error', function(error) { 
      log.info('SOCKET ERROR: ' + JSON.stringify(error));
    });

    socket.on('close', function(had_error) { 
      log.info('SOCKET CLOSED. IT WAS ERROR: ' + had_error);
    });
  });

Got those messages on middle of ingest:

info: SOCKET TIMEOUT
info: SOCKET CLOSED. IT WAS ERROR: false

But on client socket do not get closed, so client wait for response. End of ingest completed with success, response sent (on closed socket!), but client still wait.

debug: Ingested new track in 215262ms. track_id=116

No idea how to block those timeouts. Removed all timeouts from server code. Tried to add KeepAlive, no result.

socket.setKeepAlive(true);

Two questions:

How to prevent socket bultin timeout?
Is it normal for node-echoprint-server to do such long ingests? (about 200 seconds!)
Maybe better to divide this large track to few small? (if large tracks bad for echoprint)

Thanks!
