做了集群，Gateway和Register是在同一臺服務(wù)器上，BuinessWorker單獨(dú)一臺服務(wù)器，都是局域網(wǎng)，
Gateway起了2個進(jìn)程，
BuinessWorker起了8個進(jìn)程，
我們的客戶端數(shù)量是可數(shù)的，也就2千不到，但啟動服務(wù)后，status 中的 connections一直在慢慢增長，
于是我在Gateway服務(wù)中onWebSocketConnect寫了日志看是否是客戶端的問題導(dǎo)致的重復(fù)連接，發(fā)現(xiàn)并沒有新的連接數(shù)，但connections一直在漲，基本上每2秒漲1個，甚至一下子漲了10幾個連接數(shù)，慢慢的，服務(wù)器連接數(shù)上去后，導(dǎo)致客戶端掉線，目前幾臺服務(wù)器iptables都是關(guān)了的;

1，請問連接數(shù)狂漲是什么情況？
2，另外我發(fā)現(xiàn)客戶端端口后，不會走onClose方法？
