When does this happen?

IF MQLLMEngine crashes with 'No heartbeat received' error when using guided JSON schema decoding under concurrent requests, especially with complex schemas.

How others solved it

THEN Avoid using guided decoding (e.g., JSON schema) for high-concurrency workloads, as it can block the engine's health checks. If guided decoding is necessary, consider enabling `--disable-frontend-multiprocessing` to mitigate timeouts. Alternatively, reduce concurrency or simplify the schema to improve performance.
