Apache Error AH02538: Child: Parent process exited abruptly. Child process is ending xampp PHP 7

Question

I have a software project with PHP 7 on XAMPP version 3.2.2

The problem is that the Apache keeps stopping constantly

I tried put this on the httpd.conf file but the problem persist

<IfModule mpm_winnt_module>
 ThreadStackSize 8388608
</IfModule>

The error log shows this:

I appreciate your help

Answer 1

You can run this: memory_get_usage that returns the amount of memory allocated to PHP. ( https://www.php.net/manual/en/function.memory-get-usage.php )

And this: memory_get_peak_usage that returns the peak of memory allocated by PHP. ( https://www.php.net/manual/en/function.memory-get-peak-usage.php )

Then tweak ini_set('memory_limit', '16M'); (16 M in the example, just set properly depending on what you get with the previous commands).

Here is the documentation for ini_set: https://www.php.net/manual/en/function.ini-set.php

You may find interesting hints here too: Fatal error: Out of memory, but I do have plenty of memory (PHP)

If you want to edit php.ini : memory_limit is for configuring the maximum amount of memory in bytes that a script is allowed to allocate. ( https://www.php.net/manual/en/ini.core.php#ini.memory-limit )
