I am using Ubuntu 12.04 with jenkins as a continuous integration server and have SonarQube installed and setup. Sonar worked for a large amount of time, but recently the service will shutdown immediately after starting the service. I am using Sonar 5.3 and my server has 4GB RAM where most of the time only 1-2GB are occupied.
The sonar.log says:
WrapperSimpleApp: Encountered an error running main: java.lang.OutOfMemoryError: GC overhead limit exceeded

<-- Wrapper Stopped
I googled for solutions but they suggest to increase the heap-size when starting the .jar file via command line, but the file that defines the sonar-service in /etc/init.d doesnt even run a .jar file.
This looks like SONAR-7125, fixed in SonarQube 5.4. Workaround is to delete the temp folder manually before restart.
