I suggest you take a step-by-step troubleshooting approach then:
- look at the CPU/RAM state of your machine as SonarQube starts-up, see if anything stands out (or if there’s any resource starvation anywhere)
- verify JVM settings you’ve defined/modified in sonar.properties
- enable debug logs in sonar.properties if still clueless
- check sonar.log content, and most importantly check content of all files in
If still mysterious then you will have to share more input if you expect more input/help. Config files, content of logs directory, findings and things you’ve tried etc.
