gulp.src push not all files to stream

[JustBlackBird]

If a directory contains more than 16 files gulp.src pushes only first 16 and ignore others.

Here is my gulpfile.js:

var gulp = require('gulp'),
    through = require('through2');

gulp.task('list', function() {
    gulp.src('src/**/*.txt')
        .pipe(through.obj(function(file, enc, callback) {
            console.log(file.path);
            this.push(file);
            callback();
        }));
});

My package.json is:

{
  "devDependencies": {
    "gulp": "~3.8.10",
    "through2": "^0.6.3"
  }
}

My directories structure is:

src/
    01.txt
    02.txt
    03.txt
    04.txt
    05.txt
    06.txt
    07.txt
    08.txt
    09.txt
    10.txt
    11.txt
    12.txt
    13.txt
    14.txt
    15.txt
    16.txt
    17.txt
    18.txt
gulpfile.js
package.json

After I run gulp list I get the following results:

/tmp/gulp/src/01.txt
/tmp/gulp/src/02.txt
/tmp/gulp/src/03.txt
/tmp/gulp/src/04.txt
/tmp/gulp/src/05.txt
/tmp/gulp/src/06.txt
/tmp/gulp/src/07.txt
/tmp/gulp/src/08.txt
/tmp/gulp/src/09.txt
/tmp/gulp/src/10.txt
/tmp/gulp/src/11.txt
/tmp/gulp/src/12.txt
/tmp/gulp/src/13.txt
/tmp/gulp/src/14.txt
/tmp/gulp/src/15.txt
/tmp/gulp/src/16.txt

But there are no 17.txt and 18.txt files in the list!

Returning files stream from gulp task really works. Thank you @heikki
