C# 执行SETEX的Redis超时

我正在客户端服务器上使用StackExchange.Redis 1.2.6与windows服务器上安装的Redis server版本3.0.504连接。我在客户端服务器中遇到以下超时异常，导致应用程序不一致

private static ConfigurationOptions GetRedisClusterConfiguration() {
    ConfigurationOptions configuration = null;
    try {
        RedisConfigSection config = System.Configuration.ConfigurationManager.GetSection(RedisConfigSection.SECTION_NAME) as RedisConfigSection;
        configuration = new ConfigurationOptions();
        configuration.AbortOnConnectFail = false;
        configuration.ConnectTimeout = 15000;
        configuration.ConfigCheckSeconds = 60;
        configuration.AllowAdmin = true;
        configuration.ConnectRetry = 5;
        if (!string.IsNullOrEmpty(config.Servers.Password)) configuration.Password = config.Servers.Password;

        foreach(var server in config.Servers) {
            configuration.EndPoints.Add($ "{server.Host}:{server.Port}");
        }
    }
    catch(Exception ex) {
        log.Error(ex);
    }
    return configuration;
}

public static ConnectionMultiplexer Instance {
    get {
        if (instance == null) {
            lock(safetyLock) {
                if (instance == null) {
                    try {
                        ConfigurationOptions configuration = GetRedisClusterConfiguration();
                        StringWriter loginfo = new StringWriter();
                        instance = ConnectionMultiplexer.Connect(configuration, loginfo);
                        if (instance != null && !instance.IsConnected) log.Info(loginfo.ToString());
                    }
                    catch(Exception ex) {
                        log.Error(ex);
                    }
                }
            }
        }
        return instance;
    }
}

我的观察：

在我的系统中出现异常时，没有太多的CPU或内存使用 客户端服务器

我看了看慢日志，没能找到 当时的任何命令

下面是我的配置，我在整个应用程序中保持与redis的单一连接

private static ConfigurationOptions GetRedisClusterConfiguration() {
    ConfigurationOptions configuration = null;
    try {
        RedisConfigSection config = System.Configuration.ConfigurationManager.GetSection(RedisConfigSection.SECTION_NAME) as RedisConfigSection;
        configuration = new ConfigurationOptions();
        configuration.AbortOnConnectFail = false;
        configuration.ConnectTimeout = 15000;
        configuration.ConfigCheckSeconds = 60;
        configuration.AllowAdmin = true;
        configuration.ConnectRetry = 5;
        if (!string.IsNullOrEmpty(config.Servers.Password)) configuration.Password = config.Servers.Password;

        foreach(var server in config.Servers) {
            configuration.EndPoints.Add($ "{server.Host}:{server.Port}");
        }
    }
    catch(Exception ex) {
        log.Error(ex);
    }
    return configuration;
}

public static ConnectionMultiplexer Instance {
    get {
        if (instance == null) {
            lock(safetyLock) {
                if (instance == null) {
                    try {
                        ConfigurationOptions configuration = GetRedisClusterConfiguration();
                        StringWriter loginfo = new StringWriter();
                        instance = ConnectionMultiplexer.Connect(configuration, loginfo);
                        if (instance != null && !instance.IsConnected) log.Info(loginfo.ToString());
                    }
                    catch(Exception ex) {
                        log.Error(ex);
                    }
                }
            }
        }
        return instance;
    }
}

你试过这样的东西吗

configuration.SyncTimeout = 15000;
