我正在尝试 Kaa 服务器，我在 kaa-node.log 文件中发现了一些消息。我不确定这些消息是否会影响 Kaa 服务器的正常工作。
- 日志文件中的“无法为端点查找 GLOBAL 参与者”。
例如：2016-10-30 23:56:10,582 [EPS-core-dispatcher-11] WARN okksosaacApplicationActor - [[90, 73, -91, -2, 123, 48, 26, -63, 92, 70, 22 , 116, -14, 54, -122, 115, 83, -83, 61, -86]] 无法为端点查找全局参与者。
虽然日志文件中有消息，但似乎 Kaa 服务器仍然正常工作。
- org.kaaproject.kaa.server.common.dao.exception.DatabaseProcessingException：端点配置文件未订阅此主题（附加如下代码示例块的消息）
此消息似乎在向某些端点发送单播通知时发生，但这些端点不订阅此主题。我还发现这些消息发生后，CPU 负载将从 8% 增加到大约 55%。虽然 Kaa 服务器看起来工作正常，但 CPU 负载似乎保持在 50-60%。
有谁知道以上消息的含义？在第二条消息出现后，无论如何都要降低 CPU 负载。
