sonarqube failed to start with app[][o.s.a.p.AbstractProcessMonitor] Process exited with exit value [es]: 143 - sonarqube

Question

We tried to install and see features of LTS sonarqube-6.7.2. When I started sonarqube it failed to start and throwing up an error in sonar.log as below.
To make sure Elastic search memory I run command as mentioned here sonarqube-es, which was sysctl -w vm.max_map_count=262144. Is the issue with Elastic search memory or server space memory?

Answer 1

In my case, found out it was happening due to port conflict with Kafka.
SonarQube uses the embedded DB as a default DB, and its default port is 9092, which is also Kafka's default port
(saw the error in sonarqube/logs/web.log, "java.net.BindException: Address already in use").
The fix:
Uncomment and change the port of the attribute "sonar.embeddedDatabase.port" to something other than 9092.
