Apache Geode Native Client 日志显示启动本机客户端时出现连接池错误

Question

我们运行一个本机客户端，当客户端启动时，我注意到缓存服务器日志中有一个 Failed to add endpoint to pool 错误。

我使用以下方法设置日志：

CacheFactory cacheFactory = new CacheFactory();
return cacheFactory
    .Set("log-file", "Geode.log")
    .Set("log-level", "ALL")
    .Set("name", "Dealer")
    .SetPdxReadSerialized(true)
    .Create();

Geode.log 文件显示如下：

有人可以解释为什么我们会在这里看到错误吗？执行的代码在 ThinClientPoolDM.cpp 但错误似乎对客户端没有任何影响，我们可以看到确实建立了连接。虽然服务器端点似乎没有添加到处于 error 状态的池中，但我们几乎可以在说 recovering subscriptions on endpoint 后立即看到一条 fine 消息，它是同一个端点。

此代码中存在一个长期存在的错误，导致它在成功时在此处记录失败，vice-versa，这很可能是您遇到的问题。此问题已于 2020 年 4 月 6 日作为 GEODE-7930 的 PR #588 的一部分修复。请查看您的本地存储库中是否有此修复程序，如果有并且仍然遇到问题，请回复。
