File sometimes got uploaded successfully & sometimes it disappears from the /tmp directory

Question

I am running a Laravel 5.2 application with PHP 5.5 and nginx on Ubuntu 14.04.

Sometimes it got uploaded successfully without any error, also sometimes out of nowhere it produces this error.

I don't know what the problem is or what is happening. I can't reproduce the error every time. It just happens randomly!

---

Here is what I've tried (already configured):

php.ini:

post_max_size: 20M
upload_max_filesize: 20M
memory_limit: -1
max_execution_time: 60
max_input_time: 60

nginx configuration:

client_max_body_size 100m;
