出现这个问题怎么解决呢？只能重启服务？
问答执行workerman status命令后，会导致设置的socket超时时长失效
#### 执行workerman status命令后，会导致设置的socket超时时长失效
RT,我是在thinkphp6中使用wokerman执行异步任务，主要是发送TCP请求给三方接口，因为三方处理的比较慢，所以设置了1个小时的超时时间，也就是代码会在`socket_read()` 这里等待1小时，但是当我运行workerman`status`的命令后，会导致`socket_read`这里立即返回，导致我设置的超时时间就失效，我该如何避免这种情况发生
```
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
//如果运行workerman status
问答(已解决) 一个老项目停止不了，查看status 和 stop都没反应，怎么在不影响其他项目的前提下重启这项目？
websocket和tcp连不上，想看下状态但命令输入后就一直卡在那里，只能crtl+c退出，stop也一样
[root@xxxx ~]# php /www/web/workerman/start.php statusWorkerman[/www/web/workerman/start.php] status
[root@xxxx ~]# php /www/web/workerman/start.php stopWorkerman[/www/web/workerman/start.php] stop
就一直停在这没反应，不知道为什么，其他项目查status是有结果出来的
查了workerman.log，里面有很多条，看日期是几天前服务器硬盘被另一个项目写了20G错误日志占满的时间一致，不知道是怎么导致这项目无法看status和stop的？
问答webman用window服务器靠谱吗？
因为workman的soket在windows上只能限制连接256个连接数，我就怕除了这个webman还有别的系统上的限制，那小白我直接用window做服务器那就完蛋了啊。。
问答workerman 4.X daemon 方式运行莫名退出
切换到daemon模式下（命令行运行时 -d ），客户端发送文件给worker进程，worker会莫名退出（status 显示 exit），文件接收会失败。有人遇到同样的问题吗？

worker exitwith status 64000服务端在运行一定时间后会出现busy情况，但是排查了一圈发现业务内并没有造成循环的问题。
