> After Kubernetes-based agents were enabled on TC, unit test builds started to fail with OOM errors. After having inspected the heap dump, I've discovered that Kubernetes agents report to have 64 cores in their processors. Since the number of cores influences the number of threads the Raft component creates, we ended up with having more than 500 raft-related threads, which consumed all available memory.
> As a quick solution to this problem, I propose to reduce the number of threads used by the Raft component, at least in tests.
