ssl链接一个奇怪的问题

各位老师大家好：
测试Websocket并发，使用公网网络，使用ws协议链接畅通无阻，链接1万2万不成问题。
https://www.workerman.net/doc/gateway-worker/secure-websocket-server.html#%E5%88%9B%E5%BB%BAwss%E6%9C%8D%E5%8A%A1
创建wss服务之后，使用wss测试链接 死活上不去7000，即将到达7000的时候进程就退出 重新链接了
linux内核优化了 打开数限制也设置了，这是为啥？

补充：两台服务器都是用阿里云按流量付费，带宽峰值100M 配置 8 vCPU 16 GiB；ws可以上去wss可以上去 应该也不是带宽问题吧
