根因分析

服务服务器未运行,或由于高负载或QoS设置,网络延迟超过超时值。

English

The service server is not running, or the network latency exceeds the timeout value due to high load or QoS settings.

解决方案

  1. 检查服务服务器节点是否运行:ros2 node list | grep my_service_server。如果未运行,启动服务器节点。
  2. 使用'ros2 service type /my_service'验证服务类型是否匹配;如果不匹配,在调用中更正服务类型。

无效尝试

常见但无效的做法:

  1. 80% 失败

    If the server is not running, it will never respond; timeout just delays failure detection.

  2. 50% 失败

    Service list may show stale entries; the server may have crashed after discovery.
