Recursive search on a linux system (1 thread) from root including subdirectories causes 8.4 GB Ram and counting

Description

The following code:

<?php
/**
     * @throws DirectoryCreateException
     * @throws Exception
     */
    public function search($flags, $options): void
    {
        $object = $this->object();
        $data = new Data($object->data());
        if(!property_exists($options, 'name')){
            throw new Exception('Option -name not set');
        }
        if(!property_exists($options, 'directory')){
            throw new Exception('Option -directory not set');
        }
        $dir = new Dir();
        $list = $dir->read($options->directory, true);
        foreach($list as $file){
            if($file->name === $options->name){
                breakpoint('match');
            }
        }
        breakpoint($list);
    }

Resulted in this output:

15625 root      20   0 9139760   8.5g   2304 R  99.7  55.0  15:11.97 php
15625 root      20   0   13.3g  13.0g   2304 R 100.0  83.9  24:48.36 php

But I expected this output instead:

15625 root      20   0 9139760   1.5g   2304 R  99.7  3.0  15:11.97 php

What i meant is this:

I keep a list of all files on the system and searches for a match.
I can create a search from root directory and go 1 subdirectory at a time but my opinion is that searching on a root device should work like a charm without complicating stuff too much...

先使用提供的 CLI 命令、PHP 8.4.12 和 Debian bookworm 环境，然后在跟踪应用程序的 Dir::read 调用时重现内存增长。确定该行为是由 PHP 还是应用程序代码导致的，并记录一个最小可复现案例以及预期的内存行为。
