browser-use多Agent工作流卡顿，反复出现504超时错误求助

我在项目中使用最新版browser-use包（0.3.2）及Google Gemini 2.5 Pro模型，搭建了包含5个Agent的多Agent工作流，各Agent依次完成文件上传、表单填写等复杂任务后移交控制权。

近期执行时Agent频繁卡顿，一段时间后反复出现如下错误：

Retrying langchain_google_genai.chat_models._achat_with_retry.._achat_with_retry in 2.0 seconds as it raised DeadlineExceeded: 504 Deadline Exceeded.

此时Agent处于任务执行中途卡顿状态，不确定问题源于Gemini模型、LangChain重试逻辑还是browser-use的跨Agent会话管理。此前代码运行正常，近几日该问题频发。

代码示例 #

agent_configs = [
    {"prompt": BROWSER_PROMPT_ONE, "max_steps": 25},
    {"prompt": prompt_two, "max_steps": 30},
    {"prompt": BROWSER_PROMPT_THREE, "max_steps": 25},
    {
        "prompt": BROWSER_PROMPT_FOUR,
        "max_steps": 60,
        "extra_params": {
            "controller": controller,
            "available_file_paths": files_keys_names,
        },
    },
    {
        "prompt": prompt_five,
        "max_steps": 35,
        "extra_params": {
            "sensitive_data": {},
        },
    },
]

for i, config in enumerate(agent_configs):
    agent_number = i + 1
    is_last = i == len(agent_configs) - 1

    agent_params = {
        "task": config["prompt"],
        "llm": llm,
        "enable_memory": True,
        "memory_config": MemoryConfig(
            llm_instance=llm,
            agent_id=f"agent-{agent_number}",
            memory_interval=10,
        ),
        "browser_session": browser_session,
        "page": page,
        "message_context": message_context,
    }

    if "extra_params" in config:
        agent_params.update(config["extra_params"])

    agent = Agent(**agent_params)

    (
        should_continue,
        total_tokens_for_run,
    ) = await self._run_and_process_agent(
        db,
        agent,
        agent_number,
        config["max_steps"],
        is_last,
    )
