Apache Geode Native Client日志在启动本机客户端时显示连接池错误

问题描述

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出现Failed to add endpoint to pool错误。

我使用以下命令设置日志

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

Geode.log文件显示以下内容：

有人可以解释为什么我们在这里看到错误吗？执行的代码位于ThinClientPoolDM.cpp，但该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。尽管服务器端点似乎未以error状态添加到池中，但我们在说出fine后发现几乎是一条recovering subscriptions on endpoint消息，它是同一端点。

解决方法

此代码中存在一个长期存在的错误，导致该错误在此处记录失败，反之亦然，这很可能是您遇到的问题。该问题已于2020年4月6日作为GEODE-7930的PR＃588的一部分进行了修复。请查看本地存储库中是否有此修复程序，如果有，请回复并仍在解决问题。
