Delphi Linux 中的 RIO PAServer 引发 IOError 11
Delphi RIO PAServer in Linux raises IOError 11
我有一个奇怪的问题我自己解决不了：
在 Linux 上使用 Delphi 10.3 Rio Enterprise（我尝试全新安装 Ubuntu 16.04 和 Ubuntu 18.04 Desktop 和 Ubuntu 18.04 Server with GUI in VMWare Player 15) PAServer crashes with I/O Error 11 每次开始调试。我可以拉取 SDK，并且 Delphi 可以正确部署所有文件。但是尝试 运行 以崩溃和 Delphi 抱怨 GDB 服务器不再可用而告终。我可以通过手动启动 运行 Linux 主机上的程序（当然无需调试）。
它不依赖于 Linux 中的用户，它也以 root 身份发生。此外，即使在非 GUI Ubuntu 服务器上，非图形应用程序也会崩溃，始终出现 IO 错误 11。
使用 PAServer 进行调试在 OSX、Android 和 Windows 上运行良好。我当然尝试了一个非常简单的单一形式项目，没有内容但结果相同。
我用 ProcMon 追踪了 Delphi PAClient，没有这方面的证据。然后我用 strace 跟踪了 Linux 进程，它给了我这个输出：

完全修改答案。
它似乎与 vmWare Player 15 无关，但以某种方式与 Ubuntu、16 和 18 相关。在所有非 Linux OS 调试工作中，也在Rhedhat 7 和 Debian Stretch。
在 Debian 9 中，我不得不使用 Ubuntu 机器生成的 sdk，因为在 Debian 中生成时缺少一些文件。可能很容易解决，但其他 SDK 可以完成它的工作。

Ubuntu 内核 4.15.0-44 引入了这个问题，Ubuntu 将在 3 月 4 日的下一次内核更新中解决这个问题。
