1. it did not break ost. one failed CQ run on for one project does not mean that ost is broken :)
2. the build was reported as failed even though there was no actual failure as CQ did not even start to run. if you look at the error, you can see that CQ actually exited because the package was failed to be build. so no package -> no CQ run.
