Я получил эту ошибку, когда я обновил с 5.0 до 5.1.

Это было связано сhttps://jira.codehaus.org/browse/SONAR-4778, Увидетьhttp://sonarqube.15.x6.nabble.com/WARN-web-o-s-s-n-NotificationService-Unable-to-deliver-notification-td5035238.html для деталей.

Это была ошибка, и она должна была быть исправлена ​​в 5.1.1 сhttps://jira.codehaus.org/browse/SONAR-6566 как заявил Саймон Брандхоф.

Сейчас я обновился до 5.1.1 и у меня все та же проблема.
