SonarQube Scanner Hangs, and eventually failed when Multiple Projects Run Concurrently

SonarQube Version: sonar-scanner-
Environment: Linux Slave

When multiple projects (around 4-5 Jenkins projects) run at the same time, the sonar scanner hangs and Linux slave buildbox disconnects eventually, then build failed. The process is estimated to take at around 4-5hours. Is there any command to be able to get verbose logging and see what made the sonar hang when multiple build is ran concurrently?

Thanks in advance for your help. I have attached here the screenshot of the error.


Welcome to the community!

You can set the sonar.log.level or turn on sonar.verbose (details in the docs) to get more in your logs.

Are all of these jobs C++ analyses, or do the languages vary?
