根因分析

生命周期节点的 `on_configure` 回调阻塞时间超过默认超时时间（10 秒），通常是由于无限循环、死锁或硬件/外部服务的慢速初始化。

English

The lifecycle node's `on_configure` callback is blocking for longer than the default timeout (10 seconds), often due to infinite loops, deadlocks, or slow initialization of hardware or external services.

解决方案

  1. Add logging inside the `on_configure` callback to identify where it hangs. For example, insert `RCLCPP_INFO` statements at key points. If the callback waits for a hardware response, add a timeout mechanism.
  2. If the callback is waiting for a service or action, ensure the server is started before the lifecycle node attempts to configure. Use a launch file with dependencies or add a retry loop.

无效尝试

常见但无效的做法:

  1. 40% 失败

    Increasing the timeout in the launch file might allow the node to eventually proceed, but it masks the underlying performance issue and can lead to longer startup delays.

  2. 60% 失败

    Removing the lifecycle management entirely by using a regular node may bypass the error, but it defeats the purpose of lifecycle management and can cause other issues.
