Root Cause

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.

Workarounds

  1. 90% success 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.

Dead Ends

Common approaches that don't work:

  1. 40% fail

    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% fail

    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.
