# [Question]: 长对话后 QwenPaw 无响应 / [Question]: QwenPaw stops responding after long conversation

## 问题或主题 / Question or topic

当单个对话的轮数较多或上下文较长后，QwenPaw 会卡住，不再回复任何内容。
When a conversation becomes long (many turns or large context), QwenPaw gets stuck and stops responding at all.

重新开启一个新对话（使用同样的模型）则回复正常。
Starting a new conversation with the same model works normally.

这个问题在我使用的两个智能体上都相继出现。
This issue has occurred on two of my agents one after another.
