我遇到了 Jenkins Slave 在建置執行期間被終止的問題。
- 作業系統：windows 2012 R2（主從）
- Java：1.8.0_211（Mater 和 Salve）
- 詹金斯版本：2.176.2Slave
- 啟動方式：Java Web start、JNLP（連線Master啟動）
問題：我在 Jenkins 中有一個專案失敗，主要是因為從屬設備在執行期間「以 CLI 模式啟動 ServiceWrapper」後終止。找到一個子進程conhost.exe，但由於 Killing 作為後備而失敗。
這種情況只發生在專案/管道中，我有 python 腳本來 ping 內部 URL (https://URL/ping），呼叫安裝的網路模擬器工具，調整網路延遲並寫入檔案/推送到 ELK。我使用 .pac 檔案設定了互聯網代理。
它完成了專案中的所有步驟，最後從屬終止，將建置標記為失敗。
注意：我們還安裝了另一個舊版本的 Jenkins 2.76，其中相同的專案/管道工作沒有任何問題。現在我們想升級到最新的 Jenkins，我們發現從屬設備被終止的問題。我現在每次都必須關閉網路模擬器工具並重新啟動 Jenkins 服務才能使其重新上線。
