sonar starts and then stops running after 15 seconds without displaying any error - sonarqube

Question

I have installed sonar on my Ubuntu 14.04 LTS (which I am running inside windows using vagrant) by following a tutorial here
And my sonar.properties file is below
/opt/sonar/conf/sonar.properties
sonar.jdbc.username=sonar
sonar.jdbc.password=sonar
sonar.jdbc.url=jdbc:mysql://localhost:3306/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&useConfigs=maxPerformance
sonar.web.host=127.0.0.1
sonar.web.context=/sonar
sonar.web.port=9000
sonar.jdbc.driverClassName=com.mysql.jdbc.Driver
sonar.jdbc.validationQuery=select 1
sonar.jdbc.dialect=mysql
sonar.jdbc.maxActive=20 sonar.jdbc.maxIdle=5
sonar.jdbc.minIdle=2
sonar.jdbc.maxWait=5000
sonar.jdbc.minEvictableIdleTimeMillis=600000
sonar.jdbc.timeBetweenEvictionRunsMillis=30000
Once after installing I restarted, started the sonar as below
/opt/sonar/bin/linux-x86-64/sonar.sh restart
/opt/sonar/bin/linux-x86-64/sonar.sh start
Now I have checked the status of the sonar as below
/opt/sonar/bin/linux-x86-64/sonar.sh status
and output is SonarQube is running.
and after some time like 15 seconds, I have checked the status again and now the output is SonarQube is not running.
I don't what's the reason that causing sonar to shut down immediately because its not displaying any error
sonar.log(/opt/sonar/logs/sonar.log) file output

I have checked whether mysql is running or not as below and it was running and up
mysqladmin -u root -p status
Uptime: 2781 Threads: 1 Questions: 122 Slow queries: 0 Opens: 48 Flush tables: 1 Open tables: 41 Queries per second avg: 0.043
So finally I didn't understand what makes sonar to shut down after some time once it was started, and what changes to make in order to run sonar continuously and where to debug?

Answer 1

You have a missing line break here:
sonar.jdbc.maxActive=20 sonar.jdbc.maxIdle=5
Sonar can't parse the maxActive option because everything after the first = is parsed as integer. This obviously fails:
java.lang.NumberFormatException: For input string: "20 sonar.jdbc.maxIdle=5"
Simple solution:
sonar.jdbc.maxActive=20
sonar.jdbc.maxIdle=5
