After update sonar-cxx from version 2.0 to 2.1 our scan hangs after 10-12 minutes of work.
I tried it with SonarQube 8.9LTS and 9.9LTS, scanner of version 4.8.0

It works with sonar.cxx.squid.disabled=true, but it's not good decision. Because we need information for code coverage, code duplications, code lines and so on.

PS With version 2.0 of sonar-cxx process works well. But this version doesn't work with SonarQube 9.9LTS, only with 8.9. :-(
