XAMPP's MySQL on Ubuntu can't handle big amounts of data

I am developing an application in Laravel using XAMPP on Ubuntu (x64).

Whenever I am asking the database to retrieve a quite big amount of data it gives me the [2002] error ("Connection refused").

I've tested this by first doing this query:

$get_slugs = Enigmacode::where("id", "<", "250")->get(array('id'));
dd($get_slugs);

The query worked flawlessly. Then I did this:

$get_slugs = Enigmacode::where("id", "<", "2550")->get(array('id'));
dd($get_slugs);

I got "Connection refused".

I know that I am asking for a lot of data but on Windows everything worked fine. XAMPP's MySQL on Windows (the same machine) had no problems with that.

Is there any reason why this is happening?
