C# 在WPF应用程序中使用StackExchange.Redis的正确方法

我已经在我的应用程序中实现了Stackexchange.Redis，以便从Redis数据库列表中获取数据。 登录应用程序（WPF）创建一个列表，并将另一个模块（C++）获取的数据推送到创建redis db的服务器上。服务器模块将响应推送到特定于用户的列表，WPF模块在该列表中每隔10毫秒通过轮询读取数据

我创建了以下方法来执行这些任务

建造师

连接Redis

从列表中获取数据

创建连接后，我每隔10毫秒启动一个System.timer调用FetchListToProcess（）方法，该方法检查列表中是否存在任何数据，如果存在，则会相应地进行提取和处理

我遇到应用程序随机记录超时异常的问题：

此异常会停止提取数据，对于不同的用户，它会变得非常随机。。像一些人一样，它持续到2-3分钟，而另一些人可能在30-40秒后停止。 以前，所有连接的用户在同一时间同时发生这种情况，但现在发生在随机时间，用户数量随机。大约有5-10个应用程序在这些redis端口连接。 我们使用单个列表插入服务器应用程序读取的数据&每个连接的用户使用单独的列表获取数据

我试着在异常详细信息下阅读并实现链接中提到的选项，但没有成功。 请说明我做错了什么？ 是实施还是其他方面出了问题

问候，

@marc Gravell。。你能建议我看的第一件事是：

slowlog

在服务器上；这是否真的是报告服务器阻塞？
