我第一次发现这个问题是在运行 Unity3D 游戏（Velocidrone）时。当我决定监控 dmesg 输出时，我也在另一个 Unity3D 游戏（Liftoff）中遇到了这个问题；我不知道这个问题是否与 Unity 有关。
在第一个游戏中，我也遇到了“内存泄漏”，几秒钟内我的 RAM 和 SWAP 就被占满了。联系开发人员后，他们告诉我这个问题是已知的，而我是第一个报告它导致计算机完全崩溃的人。他们建议我将交换文件从 2GB 改为更大的大小。我照做了，目前情况好多了。不过，我确实遇到了另一个问题，我最初认为它与此有关，但可能不是。
当我启动游戏时，无论是通过启动器还是直接启动，我都无法验证服务器。查看我的 dmesg，我每次都看到这种情况。

游戏日志显示我进入离线模式，因为我没有连接到互联网。ping 8.8.8.8同时运行时，我可以看到我确实断开了连接。在它自行重新建立互联网之前，该问题可能会重复（或不重复）超过 1 次，但不知道为什么有时它只能尝试 1 次，有时尝试 2 次，有时尝试更多次。
我期待您的帮助来调试这个问题。谢谢
