We developed an app based on Windows SDK that launches Zoom on several PCs in a studio used for teaching. Last week, during meetings with approx 350 users, the app crashed. The app has never crashed in production before, although these were much larger meetings than we usually host. The app was relaunched and crashed again a few minutes later, relaunched again and it stayed up through meeting. The app crashed on both PCs at exactly the same times, after processing the same events from Zoom (we handle and log various events such as leave/join/activespeaker). The machines were not configured to create mini-dumps so I don’t know where the crash occurred.
Are there known vulnerabilities to large meetings in the Windows SDK? We are currently using SDK release from 2019-11-04 and I see there are two releases since then.
Do you have any suggestions for testing under load? I’ve thought about automating the web client to simulate large numbers of participants.
Thanks for any advice,
