I just installed sonarqube 6.2 on a linux server with a postgres database.
I had troubles with some databases disconnections that I apparently fixed by decommenting in the config :
sonar.jdbc.maxActive=60
sonar.jdbc.maxIdle=5
sonar.jdbc.minIdle=2
sonar.jdbc.maxWait=5000
sonar.jdbc.validationQuery=select 1
sonar.jdbc.minEvictableIdleTimeMillis=600000
sonar.jdbc.timeBetweenEvictionRunsMillis=30000
But the server keep closing randomly (~1-2h after it starts) with nothing on the logs,
==> logs/ce.log <==

<-- Wrapper Stopped
My first guess was that it might be a problem with database connexion timeouts ? But the database is installed on the same machine, and it stops really randomly :
2017.01.05 03:07:14 INFO app[][o.s.application.App] SonarQube is up
2017.01.05 05:38:06 INFO app[][o.s.p.m.Monitor] Process[ce] is stopping
2017.01.05 11:07:53 INFO app[][o.s.application.App] SonarQube is up
2017.01.05 12:36:52 INFO app[][o.s.p.m.Monitor] Process[ce] is stopping
2017.01.05 14:22:03 INFO app[][o.s.application.App] SonarQube is up
2017.01.05 15:40:38 INFO app[][o.s.p.m.Monitor] Process[ce] is stopping
Any help would be greatly appreciated, thanks
EDIT : It just crashed while I was using it, the server is swaping a lot, I will try to free some ram (btw I have sonar.web.javaOpts=-Xmx512m -Xms128m -XX:+HeapDumpOnOutOfMemoryError -server and no dump showed)
Such shutdown of SQ on Linux have been explained in the past by the Linux process "OOM killer" killing any of the 4 JVM of SQ (here it seems to be the CE's JVM) because the system is running out of memory.
You should ensure that you haven't configure SQ (by adding the max heap of each process) to consume more memory than available on the system.
