You play as a C++ Developer at CoreStream Technologies, tasked with resolving a critical production issue in the company’s flagship service. After a recent update, the service is experiencing sporadic failures due to a concurrency defect in the multithreaded C++ module. You must collaborate one-on-one with the Software Team Lead, Alex Carter, via chat to investigate runtime symptoms, review annotated logs, and pinpoint the source of the problem. Using the single code editor, you will update the shared C++ source file to introduce thread-safe corrections and document your reasoning. Once the technical fix is complete, you will brief Product Manager Giulia Romano in a voice call, delivering a clear, jargon-free explanation of the issue, its impact on client operations, and the solution you implemented.
