Sonarqube 警告web[o.s.s.n.NotificationService]无法传递通知

当我从5.0升级到5.1时，确实出现了这个错误

这是与我有关的。 有关详细信息，请参阅

这是一个bug，应该在5.1.1中用Simon Brandhof所说的方法修复它

现在我已经升级到5.1.1，我仍然有同样的问题

我没有访问Jira的权限，因此我无法向错误添加注释。 你能帮我做这个吗

您是否尝试增加MySql实例的等待超时？从SQ 5.0开始，越来越多的分析处理在服务器端完成，因此这可以解释为什么一些DB请求需要时间来执行。增加等待超时是一种解决方法，但不是解决方案。问题不在于执行时间长的请求。问题是与数据库的连接未关闭，并且在sonarqube希望传递通知时被重用。因此，如果sonarqube在2天内不发送邮件，我必须将等待超时时间延长至2天！！这是一个回归，见错误4778和6556。它应该在5.1.1中修复……我的感觉是，您可能存在一些配置问题，因为我们的SonarQube（）公共实例在MySql 5.6.19上运行5.1.1时没有遇到这样的问题。请您在问题中添加以下信息：SonarQube实例“系统信息”页面“数据库”部分的内容。@Fabrice SonarQubeTeam我已在问题中添加了数据库配置。自5.0以来，我从未更改过配置。我使用的配置与sonar.properties文件中给出的默认配置相同。是的，通知在Nemo上被激活（我每天都收到通知），我们在Nemo上从未遇到过这个问题。但也许您的实例发送的通知比Nemo多得多。能否尝试将“sonar.notifications.delay”属性（在conf/sonar.properties文件中）设置为类似“10”的值？这可能有助于减少查询数据库以发送通知所需的时间。看见
