Intermittent waitForQualityGate timeouts

Template for a good bug report, formatted with Markdown:

  • SonarQube - Version 6.7.4
  • Jenkins Plugin - 2.8

Intermittently the waitForQualityGate() which has a timeout of 10 minutes is timing out although the sonar run is complete within 2 seconds, the json task on /api/ce/task?id= shows it has been successful. There are also no errors in the ce.log, at the time of the post I also see in Jenkins
