Analysis fails with FileNotFoundException (too many open files) in PmdConfiguration.dumpXmlRuleSet(), log contains hundreds of "Fail to execute PMD"

We have a Sonar-Job on our Jenkins CI server. The job fails sometimes showing this stack trace:

I already found https://jira.sonarsource.com/browse/SONARPMD-6 which should be fixed in PMD plugin 2.4. We're using 2.5.

Hello Eduard,

The SonarSource team is no more contributing directly to the Checkstyle, PMD and Findbugs plugins. I would try to fill an GitHub issue directly on the SonarQube PMD plugin : https://github.com/SonarQubeCommunity/sonar-pmd. 

Cheers

Freddy

Hi Freddy

Thanks for the hint. Is there an overview somewhere about the status on replacing PMD rules with SonarQube rules?

Cheers,

Eduard

Hi Eduard,

This report should be helpful: http://dist.sonarsource.com/reports/coverage/pmd.html
