[Bug] Memory leak 内存泄露

[HongchengQ]

Each player occupies a significant amount of memory in this program. This is a server that has been running for 10 hours. Prior to this, the online player count remained between 10 and 30. When players exit the game, the server does not clean up the corresponding memory, resulting in excessive memory usage even when there are only two players left on the server. This is even crazier than GIO.

每一名玩家在这个程序上占用的内存都非常多 这是一个开了10个小时的服务端 在这之前在线人数保持在10-30之间 当人们退出游戏时服务端并不会清理掉对应的内存 使得即使最后服务端只有两名玩家 内存占用也非常离谱 这简直比gio还要疯狂
