Larger DICOM Files are not uploading from local to server

[ghost]

Only 50MB's file is uploading but larger files are not uploading.

I am using this code

let fileUploaded = Async.runSync(function(done) { 
    let url =  `curl -X POST http://localhost/peers/peer2/store -d *********************`;
    console.log(url);
    new Fiber(function() {
    childProcess.exec(url, function (error, stdout, stderr) {
         if (error) {
                done(error);
            } else {
                done(null, 'File uploded')
            }
    });
   }).run();
});

Sorry, this does not seem like a ruby-dicom error.
