PHP laravel include文件报 too many open files？

Question

PHP7.3，在laravel框架执行定时任务，报错提示打开文件太多，看报错像是在加载文件时报的错。

[2023-03-15 00:14:13] local.ERROR: include(/www/vendor/symfony/string/UnicodeString.php): failed to open stream: Too many open files {"exception":"[object] (ErrorException(code: 0): include(/www/vendor/symfony/string/UnicodeString.php): failed to open stream: Too many open files at /www/vendor/composer/ClassLoader.php:571)

各位大佬有解决办法嘛？

Answer 1

检查一下有没有导入的死循环

Answer 2

定时任务代码发上来。
定时任务是常驻内存吗？

Answer 3

使用 require_once 或 include_once 函数，它们只会在第一次调用时打开文件并将其缓存，而后续的调用将直接使用缓存的文件。

我看你上面报错是因为在 /www/vendor/composer/ClassLoader.php 这个文件中多次用了 include(/www/vendor/symfony/string/UnicodeString.php) 这个文件导致的
