Error messages in CE Logs- DirectoryNotEmptyException and Device or resource busy

Im looking to obtain a deeper understanding of the messages in our ce log, so they can be resolved.

  • SonarQube Version 7.4 running on Linux using Oracle as the DB
    Scanning 156 projects totaling 20,405,430 lines of code.

So far we have implemented the recycling of the sonarqube server weekly to clear the temp files and avoid performance issues.

Sample of messages:

There are hundreds of files in these temp directories, and the extensions are .pb and .txt. Here is a sample of those files:

Others contain Java code.

I want to add we a using the Community version of SonarQube.
