hyperf-admin server:watch 报错 WARNING Worker_reactor_try_to_exit

本文链接：https://blog.youkuaiyun.com/lu4506527/article/details/116859554

在使用hyperf-admin组件时，用 hyperf官方的热更新 watch server:watch 时，启动成功，但是修改任何文件都是报以下错误：

swoole官网的解释是：在约定的时间 (max_wait_time 秒) 内此 Worker 没有退出，Swoole 底层强行终止此进程。照成2个协程发生死锁。

在不使用 hyperf-admin 组件时，server:watch 没有问题。加了 hyperf-admin 组件之后，就会报错。不知道是 hyperf-admin 的BUG还是 server:watch的问题。

环境：

裸机跑环境，没有上docket
swoole 4.6.6
php 7.4
hyperf 2.0
mysql 5.7
redis 6.2

这里先记录一下，有哪位大佬解答一下。

以下是重现步骤：

安装 swoole 4.6.6

phpize && ./configure --enable-openssl --enable-http2 -with-php-config=/www/server/php/74/bin/php-config && make && sudo make install

安装成功

安装 hyperf 框架

composer create-project hyperf/hyperf-skeleton

一路 n 回车

启动项目，hyperf 框架启动成功

安装热更新 Watcher

[root@xxxxxxx hyperf-skeleton]# php bin/hyperf.php server:watch

安装 hyperf-admin

[root@xxxxx hyperf-skeleton]# composer require hyperf-admin/hyperf-admin -W

启动server:watch

[root@xxxxx hyperf-skeleton]# php bin/hyperf.php server:watch

监听成功，接下来去修改任意文件

问题重现了

个人理解大致说的是：reactor向worker进程发送终止信号，但是worker超时没有终止，报warning错误。有一个协程sleep，产生死锁。是引入了 hyperf-admin 组件之后，才出现的，不知道组件里面哪个地方产生了死锁。
