503 error on include large file

[br3t]

Hello. I need to include big (20Mb) PHP-file with two-dimensional array (about 80k rows) into my PHP-script. This causes 503 server error on LSWS. I tried to enlarge PHP memory limit to 1024Mb, but it doesn't help. It's a specific problem, because on Apache server file is included without any error.

Here is my settings:

My engine.php:

<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

include('data.php'); // <- it's about 20Mb

And my error log:

2023-09-01 10:40:44.508249 [NOTICE] [10704] [111.22.33.44:99099#example.com] oops! 503 Service Unavailable

Is the source of the included file an external source from other host?

data.php is local file:

<?php
$data = array();
$data[] = array(
    'a' => 'string',
    'b' => 'string',
    'c' => 'url',
    'd' => 'string'
);
$data[] = array(
    'a' => 'string',
    'b' => 'string',
    'c' => 'url',
    'd' => 'string'
);
...

520000 rows of code total

503 Service Unavailable can have many causes. The first thing I would suspect is that the load is too high.
If the file is included, what happens afterwards?

 

[br3t]

I need to operate this data, but I've realized what only two files enough to reproduce the problem. Engine.php consists only one include of data.php and no other code. And this generates an error. When I tried to remove some rows from data.php - only 400k left, 16Mb file - error dissappeared.

How long does it take to include this file?

Unfortunately, you haven't answered my question about what happens after the inclusion?

I get 503 error right after inclusion

Unfortunately, you haven't answered my question about what happens after the inclusion?

I get 503 error.

engine.php without include - ok
engine.php with include of shorter version of data.php - ok
engine.php with include of full version of data.php - 503

Can you split data.php?

 

[br3t]

I've splitted data.php into 2 parts 10Mb each and it worked.
But data.php is generated by another script

Are there any settings inside LSWS to proccess big php-files?

 

[serpent_driver]

The cause seems to be the amount of data. Therefore you should check your PHP settings. However, it does not necessarily have to be an insufficient PHP setting. The LSWS has PHP-independent settings that you can change via the LSWS WebAdmin, provided you have access to the WebAdmin Console. The documentation might also help you.

I discovered this page, but none of logs provided me additional information about this error.

What about these settings?

 

[br3t]

I manage server via aaPanel, so to config it I need to edit Configuration file

 

[serpent_driver]

Is this Shared Hosting?

 

[br3t]

No, it's VPS

Then, this is the way to configure LSWS: https://YOUR_SERVER_IP:7080

Login panel to server dashboard opens, but I don't know credits to log in it

 

[serpent_driver]

Ask your hosting provider or did install LSWS by yourself? If the latter, then you entered the login data during installation.
