Can't increase memory limit for PHP?

[Hoo Host 0]

Hi all, any input on this or even confirmation that it's an issue that others have encountered would be greatly appreciated:

 

I just recently made the upgrade to Uniserver Zero XIII with PHP 7.0. The issue is that half my sites (mainly WordPress but that's irrelevant) keep failing with out of memory errors. These same sites worked just fine on the older Uniserver Zero XI. I have written a little script to illustrate what is happening - PHP is ignoring the set memory limit and restricting it to some amount under 408MB. It doesn't matter if it is set in the php_production.ini file, via .htaccess, or via ini_set() in the php script itself. As you can see from the phpinfo.html output below it is configured at 2048MB (I have also tried at 512 and 1024 with no difference in results). I have tried installing the PHP 7.1 module with no luck there either.

 

Here is my phpinfo: http://hoohost.com/dev/us/phpinfo.html

 

16GB physical RAM, never close to using half of it.

 

Test script - note that the output shows that it never allows more than ~408MB (240MB after loading other local sites) even though it is set to max out at 2048MB in php,ini config:

<?php
	echo "Memory limit: ".ini_get("memory_limit")."<br><br>";
	$a=array();
	if (ob_get_level() == 0) ob_start();
	for($i=0;$i<200;$i++)
	{
		$a[]=str_pad('',1024*1024*8);
		echo "Pass ".$i.", memory used: ".number_format((memory_get_usage())/(1024*1024),0)." MB<br>";
		ob_flush();
		flush();
	}
?>

Output: after starting UniServer Apache without loading any other local sites:

I found a solution! But since nobody is capable of replying I'm not going to explain. Good luck!
