服务端异常退出 "panic: concurrent write to websocket connection"

[deadblue]

你正在使用哪个版本的 V2Ray？

服务端：v5.14.1
客户端：

• PC: v5.14.1
• 手机：v2rayNG v1.8.19 / 其他不明

你的使用场景是什么？

服务端是供几个朋友在一起用，在某一时刻出现 panic 后服务端挂掉，具体在做什么不清楚。

你看到的异常现象是什么？

服务端出现 panic 后非正常退出，监听的 Unix Domain Socket 没有被删除，导致 systemd 自动重启失败。

你期待看到的正常表现是怎样的？

不出现 panic，或出现 panic 后可正常删除 sock 文件再退出。

请附上你的配置
