Sonarqube background tasks running forever

问题

We have running SonarQube 5.6.4 for a while now. Then we observed suddenly that the queue of background tasks is increasing. In the logs we see messages like that:

2017.07.24 13:56:10 INFO  [o.s.s.es.BulkIndexer] 0 requests processed (0 items/sec)

Every minute one log entry.

Other tasks started then are failing with:

org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes were available: [[sonar-1498219166409][3QkGfCI8RUSn6vapRi5SSg][a2d477fdfe7a][inet[/127.0.0.1:9001]

I do not know how to find anything which is causing the error. Nothing has changed in the configuration.

I restarted the server but nothing changed.

What is remarkable for me is the number of ports which seems to be opened by elastic search:

tcp        0      0 localhost:etlservicemgr localhost:53058         ESTABLISHED 24/java

tcp        0      0 localhost:etlservicemgr localhost:52922         ESTABLISHED 24/java

(really five times more)

Has anyone an idea how to find the cause of the problem?

sonarqube.properties has default values. Only changes are:

sonar.security.realm=LDAP
sonar.security.savePassword=true
sonar.security.updateUserAttributes=true
sonar.authenticator.downcase=true
sonar.authenticator.createUsers=true

and the LDAP configuration.

回答1:

While I still not understand why the taks was stuck and did not throw an exception our problem seems to be solved by increasing the heapspace for the worker from 500MB to 1GB:

sonar.ce.javaOpts=-Xmx1024m -Xms128m -XX:+HeapDumpOnOutOfMemoryError -Djava.net.preferIPv4Stack=true
