Question

我们有一个jenkins工作被配置为从gerrit获取更改来执行CI，有时这个工作随机失败以执行Git操作，就像在gerrit服务器上克隆或获取一样。 gerrit服务器由带有PGBouncer的postgres数据库提供支持。服务器的SSHD日志包含以下日志消息。

    [2018-05-19 17:15:27,405 +0000] 7f660610 username a/1000024 git-upload-pack./sampleproject 1ms 300002ms killed

应用程序日志有以下堆栈跟踪，它来自jgit或lucene。

 [2018-05-19 17:15:27,636] [SSH git-upload-pack '/sampleproject' (username)] WARN  com.google.gerrit.server.git.SearchingChangeCacheImpl : Cannot fetch changes for sampleproject

以前有人遇到过这个问题吗？或者我们可以做些什么来确定问题？

Answer 1

我们还遇到了与Gerrit的ssh连接的一些问题。这是一段时间以前，所以我不记得确切的错误。但我们使用了Gerrit的旧版本（2.10或其他）。

我们的解决方案是使用https协议代替ssh进行远程git操作。

从gerrit克隆存储库有时会失败
