> URL: https://issues.apache.org/jira/browse/NIFI-14673
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Reporter: Mark Payne
> Assignee: Mark Payne
> Priority: Major
>
> When using a Process Group configured with a Stateless Execution Engine, each
> time that you stop/start the Process Group, we appear to increase the number
> of bulletins per log message by 1.
> For example, create a flow with a GenerateFlowFile -> LogMessage and
> configure for Stateless Execution Engine. Set Bulletin Level on LogMessage to
> INFO.
> Run the stateless flow, and the message will be logged once.
> Stop it and run again. Now, for each FlowFile, there will be 2 bulletins.
> Stop and run again. Now, for each FlowFile, there will be 3 bulletins, and so
> on.
