Why does the analysis fail at Load project repositories? - sonarqube

Question

I'm using SonarQube 5.1 and sometimes am able to complete the analysis but most of the times it is failing.
I tried to set this in sonar.properties:
sonar.jdbc.maxWait=400000
sonar.preview.readTimeout=400000
I'm using mysql as SonarQube database and there is only 60% of disk space utilized.
Still, when running an analysis, I get these logs and the analysis fails:
[sonar:sonar] 06:25:38.262 INFO - Initializing Hibernate
[sonar:sonar] 06:25:49.056 INFO - Load project repositories

Answer 1

SonarQube 5.1 is an old version of SonarQube, the latest LTS being 5.6.
I recommend you to upgrade to 5.6 in order to be able to get some help.
