[Bug] 事件循环触发会话锁异常 acquired session lock for llm request.

[FeiLongQi]

Description

异常：
在私聊中向机器人发送除图片外的文件(如xlsx或pdf文件)或引用这类文件的消息，导致触发会话锁后无法自动触发文件处理工具，直到30分组后超时释放会话锁。关闭所有第三方插件后仍然出现相同情况。

触发频率：频繁，十次有九次会复现该情况

部分异常时日志：（event_loop_watchdog.log没有日志被记录）

AI给出的理由是没有触发agent的关键词，解决方案是关闭所有第三方插件，然后文字和文件同时发给机器人，并在文字中明确“读取这个 Excel 文件，提取里面的内容”，我在尝试关闭插件重启所有关联的容器并/reset上下文后还是不行

Reproduction Steps

1.向机器人同时发送文字+文件消息，总是触发会话锁异常，无法自动触发文件处理工具，也无法正常处理文字消息

2.向机器人先发送文字再发送文件，总是触发会话锁异常，无法自动触发文件处理工具，也无法正常处理文字消息

3.向机器人先发送文件再发送文字，频繁触发会话锁异常，偶尔可以正常调用工具上传文件至沙箱并分析文件内容和处理文字消息。但几乎每次仍然是触发会话锁异常，无法自动触发文件处理工具，并回答没看到文件。沙箱内确实没有文件，但Astrbot的缓存目录能看到(astrbot-data/_data/temp)

你先判断一下是不是你模型提供商的问题。我没看出这个日志有啥问题。 acquired session lock for llm request 是正常的非报错日志。

你先判断一下是不是你模型提供商的问题。我没看出这个日志有啥问题。 acquired session lock for llm request 是正常的非报错日志。

一、明白你提到的“acquired session lock for llm request 是正常的非报错日志”，但是正常情况下在这条之后应紧跟的应该是是llm和angent调用工具的日志才对，可是没有，反而是锁住直到超时也没有任何调用工具的记录导致无法进行下一步或主动释放会话锁。

二、之前有测试更换过不同模型和模型提供商但都是相同问题，今天(2026/08/10 AstrBot版本4.27.2)又试了一下还是一样结果。
1.模型提供商: deepseek 模型: deepseek-v4-flash

2.模型提供商: openrouter 模型: gpt-5.6-luna和gpt-5.6-sol （sol和luna配置相同因此只展示luna）
