I found a similar unsolved discussion that might be related to your issue: “Navigating the ‘Stop Responding’ Prompt in Applications” [1]. Additionally, there was a closed issue related to errors during conversation: Encountered an error during the conversation；"ERROR:core.application_manager:Validation Error when generating", which was resolved by a pull request that fixed an issue with Azure OpenAI stream response usage [2].

Regarding the mechanism in Dify's codebase that handles stopping a response, it involves the controlStopResponding prop in the Result component. When this is set, the useEffect hook triggers a function to update the responding state to false, effectively stopping the response process. The handleStop function also plays a role by setting a flag, updating the responding state, and aborting any ongoing requests [3][4].

If you're experiencing repeated responses, it might be worth checking if there are any configuration settings affecting chatflow behavior. In Dify's self-hosted Docker setup, settings like TEXT_GENERATION_TIMEOUT_MS and GUNICORN_TIMEOUT can influence chatflow stability [5]. Adjusting these settings might help mitigate the issue.

FYI

  • Check the model settings, especially the repeat penalty
  • Please provide A minimal DSL to reproduce this problem
  • Upgrade to latest verssion.

@crazywoola,
Thanks!

  • Check the model settings, especially the repeat penalty
    The repeat penalty parameter is not enabled.
  • Please provide A minimal DSL to reproduce this problem
    My chatflow is a bit complicated.
    Because the problem only occasionally arises, I think it may not be related to the configuration of workflow.

It seems system crashed, and repeats output the last sentence constantly, Just like there is an output requirement for it to do so again and again.
I am certain that such a request has not been made anywhere else.

We will not output duplicated message if the system is crashed, maybe it's the problem of the LLM side.
