Invoking method with ucfg - GC overhead limit exceeded

SonarQube Server / Community Build

Hello,

During “Invoking method with ucfg” (on C# code analysis) following error occurs systematicaly “java.lang.OutOfMemoryError: GC overhead limit exceeded”.

  • Sonar version : 7.9.1.27448
  • Sonar c# scanner : 7.15 (build 8572)
  • Analysis additional properties :
    sonar.cs.vscoveragexml.reportsPaths=TestResults/**/.coveragexml
    sonar.inclusions= **/    .cs,Scripts/*.js
  • Quality profiles : C# Sonar way BuiltIn

It happens since we bought the “Developer Edition”, previously with “Community edition” everything goes well and analaysis takes approxiamtivaly 15 min.
Analysis don’t failed on a specific method and analysis time is not constant as you can see on following logs :

As explain in the documentation, we allocate a larger heap but there is no improvement.

Server memory configuration :

  • Physical : 42(GB)
  • Heap Max
    - Web : 3072(MB)
    - Compute Engine : 6144(MB)
    - Search Engine : 31744(MB) (maximum allowed according documentation)

Monitoring don’t show 100% usage of memory (same for CPU).

Any help would be appreciated.

Hi,

With the “Developer Edition”, you get new security rules. Your logs seem to indicate that the error you get is related to those security rules.

The error happens on the scanner side (“Error during SonarQube Scanner execution”), so the “server memory configuration” is not relevant here… You should look into the SONAR_SCANNER_OPTS environment variable which is mentioned in the troubleshooting section of the scanner documentation.

Thk’s for your answer Pierre-Yves.
I’ll try to tweak SONAR_SCANNER_OPTS environment variable and tell you if it’s better.

4

We try following value :

SONAR_SCANNER_OPTS=-Xmx8192m

But there is no improvement.

Is there a way to disable these new security rules ?

5

Maybe you can check that your setting was taken into account by looking at the line of the logs where you had something like Final Memory: 16M/1243M: you should now see a much higher value.

To disable the related security rules, you have to adjust the quality profile used for the analyzed project. Look for the C# rules which belong to the “Repository” named “Security SonarAnalyzerC#” (example) and disable them in the quality profile of your project.

6

Finally increasing SONAR_SCANNER_OPTS is the solution to our problem (first time we increase it, it doesn’t work because we forget to reboot the server).

Thk’s for your help Pierre-Yves.

Thanks for letting us know!
