Laravel会随机尝试访问一个不存在的符号链接

Question

首先，请允许我解释我的部署是如何工作的：

1. 获取最新代码并放入临时目录
2. 获取epoch格式的当前时间戳并存储在变量中
3. 使用时间戳的名称创建一个新目录，并将最新代码移动到该目录中
4. 创建指向vendor和storage目录的符号链接。同时为.env创建符号链接
5. 进入时间戳目录，运行一些Composer和Laravel命令
6. 将时间戳符号链接到名为current的目录，Nginx将访问该目录
7. 设置正确的所有权和权限
8. 重新启动PHP-FPM和Supervisor
9. 删除旧版本

偶尔我会遇到这样的错误：

The stream or file "/usr/share/nginx/html/sample_directory/releases/1617243734/storage/logs/laravel-2021-04-07.log" could not be opened in append mode: failed to open stream: Permission denied

其中1617243734是不再存在的旧时间戳目录。

有人知道这个问题的原因吗？

以下是部署文件：

感谢@N69S的评论。用php artisan queue:restart代替supervisorctl restart all似乎可以阻止错误的发生。
