java.io.IOException：無法運行程序“git”：錯誤=11，資源暫時不可用

Question

使用 GOCD 管道。 我們有兩個節點，其中一個可以很好地克隆代碼，而這個舊節點則沒有。 我們看到無法運行程序“git”：錯誤=11，日志中的資源暫時不可用。 是否有一些我可以檢查的配置？

此問題已通過重新啟動 go 代理解決。 出現了一個新問題，但此問題已通過以下方式解決。

1. 登錄到 GoCD 用戶界面。
2. 點擊“代理”
3. 選擇需要重啟的代理
4. 單擊禁用按鈕
5. 刷新頁面。
6. 您將看到該代理已禁用，並位於列表的最后一個
7. 復制“代理名稱”。 這是主機代理。 使用 Cada 憑據登錄此主機。
8. 運行命令：sudo su -
9. 現在執行： sudo /etc/init.d/go-agent1 restart （注意：agent 后的最后一位數字將根據 GoCD UI 中的 Agents/“sandbox” 值更改） 以上命令將重新啟動代理
10. 現在返回 GoCD UI，選擇禁用的代理並單擊啟用。
11. 刷新頁面，代理應該回到空閑狀態。重新啟動 GoCD 代理：
