linux - Linux 中的 Delphi RIO PAServer 引发 IOError 11

Question

我有一个我自己无法解决的奇怪问题:

在 Linux 上使用 Delphi 10.3 Rio Enterprise(我尝试在 VMWare Player 15 中全新安装 Ubuntu 16.04 和 Ubuntu 18.04 Desktop 以及带有 GUI 的 Ubuntu 18.04 Server ) 每次我开始调试时，PAServer 都会崩溃并显示I/O Error 11。我可以提取 SDK，Delphi 可以正确部署所有文件。但是尝试运行以崩溃和 Delphi 提示 GDB 服务器不再可用而告终。我可以通过手动启动来在 Linux 主机上运行程序(当然不需要调试)。

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 跟踪了 Delphi PAClient，没有这方面的证据。然后我用 strace 跟踪 Linux 进程，它给了我这个输出:
