與 Jack 伺服器 (77) 的通信錯誤導致 Jenkins 建構失敗

我正在創建一個 CI 建構來編譯我們的自定義 Android ROM / OS，並且在嘗試進行自動建構時，我在 Jenkins 中收到了一個奇怪的錯誤。當我手動建構時，問題不會發生，這讓我相信它與 Jenkins 有關，但我似乎無法弄清楚原因。

通過研究，似乎很多人對與記憶體相關的 jackserver 存在問題，但我正在建構的機器有 64GB 的 RAM 和 24 個執行緒。加上我得到的錯誤是一個通信錯誤：

Communication error with Jack server (77) 

下面是我從 Jenkins 那裡得到的錯誤日誌：

另一個痛苦是 Jackserver 日誌文件中沒有任何記錄，當我執行時：

jack-diagnose

我沒有得到任何有價值的東西。任何幫助，將不勝感激。

最後超級簡單的修復，只需要重新啟動伺服器，我的建構現在就完成了。
