I am working on a django project and it has 20+ apps in it which means i have to run tests of 20+ apps which includes 3000+ tests. So I decided to make subjobs in my pipeline and now running 20 jobs for the unit tests on commit. But the issue is that when more than 1 developer commits and tests runs for both, pipeline get stucks. Pipeline runners are registered on a VM of 32 CPU cores and 24 GB of RAM. CPU utilization becomes 100% and jobs stuck(deadlock).
