N8n kafka trigger node execution stuck in running status

Describe the problem/error/question

i have a simple workflow, kafka trigger node → do nothing node.
using MAC OS Ventura 13.5, i have kafka installed via homebrew as service.
using built-in kafka console producer with command:

kafka-console-producer --topic kafka-deep-dive --bootstrap-server localhost:9092

just feeding a simple event copy/paste enter:

{“id”: 1}
{“id”: 1}
{“id”: 1}
{“id”: 1}
{“id”: 1}
{“id”: 1}
{“id”: 1}
{“id”: 1}

What is the error message (if any)?

when i do the copy-paste-enter quickly multiple times, sometimes executions get stuck with status running. i am assuming its not a n8n-gui related problem, i also checked with

select * from execution_entity ee where ee.“workflowId” = ‘9WaZ2DgfbBMoRGqI’ and ee.status <> ‘success’;

i can see executions with status running.

Any ideas ?
