尝试从ant运行Sonar时，由于SocketTimeoutException而导致零星失败。
设置：我已经在配置为与Postgres 9.2一起运行的RHEL 6盒子上运行Sonar 4.0。我使用Jenkins 1.544每晚构建175个项目。我已经让Jenkins在从机上使用单个执行器串行构建项目但是最近我通过swarm添加了第二个slave，所以现在我有两个节点（每个都有一个执行器），并行构建。我使用声纳蚂蚁任务从蚂蚁运行声纳，这在很大程度上运作良好。
当我只有一个奴隶时，我偶尔会在尝试加载引导程序属性时因为SocketTimeoutException而失败。现在我已经添加了第二个节点，这似乎更频繁地发生了。有趣的是，当我使用ant在命令行上构建项目时，我也看到了同样的失败。这似乎不是服务器资源问题。我是声纳服务器的唯一用户，我能够在没有任何实际负载的情况下得到此错误。
这是今天早上从命令行运行时得到的堆栈跟踪：

我查看了sonar access.log，可以看到初始连接并从上面列出的故障中重定向：
172.20.2.172 - - [01/01/2014：09：45：25 -0500]“GET / api / server / version HTTP / 1.1”200 3“ - ”“Ant / 2.1” 172.20.2.172 - - [01/01/2014：09：45：26 -0500]“GET / batch_bootstrap / index HTTP / 1.1”302 125“ - ”“Ant / 2.1” 172.20.2.172 - - [01/01/2014：09：45：26 -0500]“GET /deploy/bootstrap/index.txt HTTP / 1.1”200 3899“ - ”“Ant / 2.1”
有趣的是我稍后看了一下日志，似乎在我开始构建后30分钟显示连接失败：
172.20.2.172 - - [01/01/2014：09：45：25 -0500]“GET / api / server / version HTTP / 1.1”200 3“ - ”“Ant / 2.1” 172.20.2.172 - - [01/01/2014：09：45：26 -0500]“GET / batch_bootstrap / index HTTP / 1.1”302 125“ - ”“Ant / 2.1” 172.20.2.172 - - [01/01/2014：09：45：26 -0500]“GET /deploy/bootstrap/index.txt HTTP / 1.1”200 3899“ - ”“Ant / 2.1” 172.20.2.172 - - [01/01/2014：10：16：20 -0500]“GET / batch_bootstrap / properties？dryRun = false HTTP / 1.1”401 41“ - ”“声纳 空/空“
现在我正在使用LDAP插件来针对活动目录对声纳用户进行身份验证，并且我已经读过这可能会导致一些缓慢，可能导致超时。我添加了ncsd，但没有注意到任何改进。我也升级到使用sonar-ant-task-2.1.jar，但没有看到变化。我可以从我的浏览器访问/ batch_bootstrap / properties？dryRun = false，虽然有时它需要比其他人更长的时间。如果我重新运行失败的工作，它几乎总是在第二次尝试时成功。
我不确定下一步该尝试什么。我想扩大群集节点的数量，但我担心这只会导致更多的失败。我不想告诉开发人员忽略构建失败的电子邮件。由于工作的数量，我能够定期遇到这个问题。如果有人有他们认为有助于避免或隔离问题的日志记录或配置更改，我可以尝试使用它们。
谢谢 - 山姆
更新：我创建了一个短脚本来获取/ batch_bootstrap / properties？dryRun = false并使用curl将结果发送到/ dev / null。我将卷曲 - 最大时间设置为2秒并将其放在cron上，每2分钟运行一次。几乎每个请求都在2秒超时之前完成（48小时内只有26次失败，所有这些都是从00:30 - 01:00开始，当时我正在运行一些维护任务）。因为我开始以这种方式ping服务器，所以我没有因为SocketTimeoutException而导致更多的构建失败。我不是真的喜欢这个解决方案，但它似乎现在正在工作。如果有人尝试，我仍然对替代品感兴趣。
更新：我能够退出cron的频率而不是每5分钟运行一次而不会发现问题。当我尝试仅运行它10分钟时，我再次看到SocketTimeoutException失败。我也进行了一般的yum更新以获得良好的衡量标准，但显然没有改进。
谢谢 - 山姆
更新：当弹性搜索作为一个单独的进程被分解时，Sonar 4.5会逐渐变得更糟。在声纳日志文件中，我遇到了其中几个故障：
2014.12.24 03:42:28 ERROR web[o.s.s.s.SearchClient] could not execute request: org.elasticsearch.action.get.GetRequestBuilder@48c9ec56
org.elasticsearch.client.transport.NoNodeAvailableException: No node available
我随着时间的推移记录了负载，发现它在夜间构建周期中比我预期的要高。除了声纳失败之外，我还没有看到任何其他奇怪的行为。最近有一些新的硬件可用，所以我将声纳全部移动到一个新的盒子上。由于这样做，我没有看到任何与超时相关的构建失败。
因此，如果有人看到类似的错误，此类错误似乎表明您需要投入更多资源。
谢谢 - 山姆
