用的是workerman框架，我自定義了一個(gè)Server類(繼承自Worker), 但是運(yùn)行起來(lái)后，onWorkerStart和onMessage都沒(méi)問(wèn)題，但是用php start.php reload，腳本就卡住了，后來(lái)一檢查，發(fā)現(xiàn)似乎是php start.php start跑完后，有進(jìn)程沒(méi)跑完！因?yàn)楫?dāng)我按Ctrl+C停止進(jìn)程后，能進(jìn)入處理reload的地方了，所以不知道問(wèn)題在哪里，能幫忙看下嗎，感激不盡。

Server.php參考Gateway類改的！
?
我經(jīng)過(guò)斷點(diǎn)調(diào)試，已經(jīng)跑完了Worker::run()，static::$globalEvent->loop();

這句話也跑了！然后我就知道去哪里了，應(yīng)該是進(jìn)入正常的事件循環(huán)吧，可是為何reload無(wú)法得到處理呢？還請(qǐng)大神解答下, Thank you!
