Agent stops responding during multi-agent orchestration workflow

(0) ShareShare

Posted on by

Hello everyone, 

I'm working in copilot studio and i spotted the following issue.

My orchestrator agent becomes completely unresponsive during multi-agent workflows. It doesn't just fail to complete tasks, it stops answering to any prompts whatsoever.

Expected Behavior:
The orchestrator calls multiple agents and returns a final consolidated report.

Actual Behavior:
After a certain point in the workflow, the agent stops responding to anything. Even if I send new prompts or try to change the conversation topic, I get no response at all. The agent appears to be stuck and won't acknowledge any input.

The Core Issue:
It's not that the agent fails at its task. It's that the agent becomes completely silent, no error messages, no partial responses, nothing. It's as if the session is frozen.

 

Anyone ever noticed this behaviour? Thank you very much.

 

 

I apologize for the messages in italian but for your reference "genera il report" means "generate the report".

    The orchestrator becoming completely unresponsive in a multi-agent workflow is typically caused by a deadlock situation, where one of the agent calls does not
     
    return (due to looping, timeout, or context limits), and the orchestrator waits indefinitely.
     
    Since no timeout or fallback is triggered, the session appears frozen with no response.
     
    The solution is to introduce timeouts, limit agent chaining, prevent recursive calls, and add logging to identify which agent is causing the stall.
