php ZipArchive addfile not work

Question

Here's my code

<?php
error_reporting(-1);
ini_set('memory_limit','1G');

$zip = new ZipArchive();
if ($zip->open(__DIR__.'/xxx.zip') === TRUE) {
        echo __DIR__.'/CPInfo.txt'."\n";
        $zip->addFile(__DIR__.'/CPInfo.txt', 'newname.txt');        
        $x =  $zip->close();
        var_dump($x);
        echo 'ok';
} else {
        echo 'failed';
}
?>

I have run command

[root@localhost]# php test.php 

And the output is

/data/yyy/CPInfo.txt
bool(true)
ok

No errors are given while adding the txt into the .zip. When I open xxx.zip, nothing is changed. File xxx.zip contains more than 1000 files and 100 folders

When i remove 900 files from xxx.zip and run this script again, it's work.

What am I doing wrong?

file open limit

ulimit -a
