Please treat this ticket similar to how you would treat a BF that needs to be investigated. For context, STM is actively working with a 3rd party (Antithesis) via PM-2446 to gather additional test coverage reports. Antithesis ran their network fuzzing against binaries we’ve provided them and as a result found this bug. Once you’ve had a chance to investigate this bug, please drop a comment and let us know whether it fits into the following categories: 1. a real server bug, 2. a bug in our test infrastructure, or 3. a bug in Antithesis’ environment.
Please let STM know if you have any questions (reach out in #pm-2446-leverage-antithesis).
A bug has been detected in Antithesis:
