与 Jack 服务器 (77) 的通信错误导致 Jenkins 构建失败

Question

我正在创建一个 CI 构建来编译我们自定义的 Android ROM/OS，当我尝试进行自动构建时，我在 Jenkins 中收到一个奇怪的错误。当我手动构建时，这个问题没有发生，这让我相信它与 Jenkins 有关，但我似乎无法弄清楚原因。

通过研究发现，许多人都遇到了与内存相关的 jackserver 问题，但我正在构建的机器有 64GB 的 RAM 和 24 个线程。另外，我收到的错误是通信错误：

Communication error with Jack server (77) 

以下是我从 Jenkins 获取的错误日志：

另一个痛苦是 Jackserver 日志文件中没有记录任何内容，当我运行时：

jack-diagnose

我没有得到任何有价值的东西。任何帮助我都会很感激。

最后非常简单的修复，只需要重新启动服务器，我的构建就完成了。
