GC overhead limit exceeded running background task in version 5.5

问题

I am running SonarQube 5.5 with the following wrapper config settings.

wrapper.java.initmemory=3
wrapper.java.maxmemory=4096

I am still getting the following stack trace, this project has run successfully with sonarqube 5.3.

回答1:

Memory adjustments must be made in sonar.properties:

sonar.web.javaOpts (for Web Server JVM)
sonar.ce.javaOpts (for Compute Engine JVM)
sonar.search.javaOpts (for JVM running ElasticSearch).

In your case the memory exception occurs in a background task so it relates to Compute Engine (see SonarQube architecture for more insight).

Settings in wrapper.conf are not relevant here and should be left untouched (hence the # DO NOT EDIT THE FOLLOWING SECTIONS warning in the file).
