When does this happen?
IF Sending two POST requests to the /v1/chat/completions endpoint with the same tool function name causes the model to generate tokens indefinitely without returning a response, consuming maximum GPU power.
How others solved it
THEN Use unique tool function names for each request (e.g., append a random suffix) or downgrade the vllm server to version v0.10.2 which does not exhibit this bug. If using a newer version, monitor for a fix in later releases.
// Example workaround in Python: generate a unique name per request
import uuid
tools[0]['function']['name'] = f"get_weather_{uuid.uuid4().hex}"Related patterns
