git - Jenkins "Error cloning remote repo ' 起源 '"and "无法分配内存”

Question

我在通过 webhook 与 GitHub 连接的服务器上运行 Jenkins。不幸的是，我的构建偶尔会失败，我不知道为什么。有时重新启动 Jenkins ( sudo service jenkins restart ) 可以解决问题，有时则不能。服务器运行 Ubuntu 16.04 nad Nginx 作为代理。是什么导致了这个问题，我该如何解决？

使用df -h或 du -sh $JENKINS_HOME检查是否有足够的内存供 Jenkins 分配。
