我们几个月来一直在用SonarQube分析我们的项目，没有任何问题。从今天早上开始，分析失败了这个错误：
Unable to request: /batch_bootstrap/properties?project=TalkManagement:TalkManagementService&dryRun=false
自从我们将Amazon EC2实例升级到Ubuntu 14.04和Oracle JDK8以来，这种情况正在发生。我们针对MySQL数据库Maven 3.1和Jenkins 1.571运行SonarQube 4.3.2。
以下是我们项目中运行Maven的日志：

直接通过浏览器或卷曲访问http://ec2-0.0.0.0.compute-1.amazonaws.com:9000/batch_bootstrap/properties?project=TalkManagement:TalkManagementService&dryRun=false时，响应确实很慢但从不超过10秒。
修改实际上，在分析运行时获取此网址时，可能需要一分钟才能返回答案！
我们已尝试将以下属性添加到pom.xml文件中：
<sonar.dryRun.readTimeout>60</sonar.dryRun.readTimeout>
<sonar.preview.readTimeout>60</sonar.preview.readTimeout>
它看起来并没有帮助。
这是一个多模块项目，在最后一次失败之前，已在其他模块上成功调用/ batch_bootstrap / properties URL。
有什么想法吗？
谢谢！

升级到Sonar 4.4，Maven Sonar插件2.4和Jenkins 1.574会得到相同的结果。
答案 0 :(得分：1)
事实证明，EC2实例已经过载（CPU和内存都已浮动），并且Sonar无法在60秒内回答/ batch_bootstrap / properties URL，因此失败。我们迁移到更大的EC2实例，问题已经消失。
答案 1 :(得分：1)
或者只是试试这个，
select * from semaphores
这将列出卡住的构建，您将能够看到项目名称，kee。如果有任何行并且与您的项目相符，则记下该ID。然后从信号量表
中删除它delete from semaphores where id = $id
有时候，当jenkins杀死你的工作时，你会遇到这个问题。
