error observed
Concurrent analysis of .net code fails intermittently. A while ago we found that concurrent analysis of .net builds failed on our build servers. We found this https://docs.sonarqube.org/display/SCAN/Miscellaneous+Advanced+Usages page and followed the instructions as given, which worked. The last couple of weeks we have started seeing this error:

A search for that error gave us this https://github.com/SonarSource/sonar-scanner-msbuild/issues/550 which seems to be a similar issue for Gitlab CI.

steps to reproduce
Start multiple analysis of .net code concurrent.

potential workaround

  • None implemented.
  • We could reduce the number of build agents available for .net builds to one pr. server.
  • We could create a number of new service accounts such that each TFS build agent runs with a separate account.

Hi @PeterKristiansen,

Thanks for the feedback. I created a ticket to track the progress of this bug:

For concurrent analysis we usually recommend using different user accounts for the build agents that are configured on the same machine and I think this is the best way to workaround the problem. If you have large build machines with a lot of processing power it does not make much sense to reduce the number of agents…

Hi,

Yes, we are aware of the workaround. But in my opinion it is closer to an error. Are there any plans to fix this issue?
