StackExchange.Redis.RedisTimeoutException: Timeout #6559

User avatar

Leonardo.Willrich created

Hi,

When I am deploing my application I am getting this error: StackExchange.Redis.RedisTimeoutException: Timeout. In my development environment it doesn't happen.

It only happens for Caches used by AbpZero framework (i.e. AbpZeroTenantCache, AbpTenantSettingsCache). Using caches created by my routines I am not getting any issue.

I have already read the article http://stackexchange.github.io/StackExchange.Redis/Timeouts, but so far I have any idea how to fix it.

Any idea how to fix those exceptions? My log files is getting full.

Best regards!

Full exception:

    @Leonardo.Willrich

    It is a hard one to figure out.

    • Does your data for the dev environment and server are same ?
    • You can also check Window's Event Viewer to see if is there any helpful error message.

    Hi @ismcagdas

    They are different databases, however, almost the same data. The database and tables are really small compared with caches that I use in my routines. I am getting erros only in apb routine.

    I will try Windows's Event Viewer.

    Guys,

    I am still struggling to fix it. My logs have tons and tons of ERROR with Timeout, and only for "AbpUserSettingsCache".

    Some idea?

    In additional,

    I realized that in my appsettings.json I have these configuration:

    "Abp": { "RedisCache": { "ConnectionString": "localhost", "DatabaseId": -1 } },

    And in my preInitialize() method I have these lines:

            //Uncomment this line to use Redis cache instead of in-memory cache.
        //See app.config for Redis configuration and connection string
        Configuration.Caching.UseRedis(options =>
        {
            options.ConnectionString = _appConfiguration["Abp:RedisCache:ConnectionString"];
            options.DatabaseId = _appConfiguration.GetValue<int>("Abp:RedisCache:DatabaseId");
        });

    Maybe is there something wrong with that?

    Hi,

    DatabaseId: -1 is refered to Redis Default database. It shouldn't be a problem.

    Hi ryancyq

    The most strange is in my local machine, development environment, it works fine. Only when it is running in our non-production environment with the application published in a ISS server it happens.

    Some idea what is going on? Any configuration maybe I am missing?

    Do you have these config in your appSettings.Production.json?

    "Abp": {
    "RedisCache": {
        "ConnectionString": "localhost",
        "DatabaseId": -1
    }
},

    I don't have. I have only appsettings.json. I always delete the others appsettings files. Should I have it? Others parameters are being reading from appsettings.json normally.

    @Leonardo.Willrich Does it always make this error when you publish it to a production environment?

    @maliming

    Yes, always. It is leaving my log file full. It isn't a production environment, it is a non-production, but it is quite similar to a production environment. My application isn't realease to production so far. I am really worried if it can be a issue or not, that is the reason I am trying to tidy it up.

    At this moment, there are only 2 users using the application, in 3 hours the log has more than 1 mb only with this Redis Cache error.

    Are you convenient to share your project source code, let us reproduce this problem?

    @maliming Do you have a contact? email or skype? The project is quite complex, it is logged in two different databases and for security reason I am not able to allow outside connections. But, maybe you can connect in my enrironment remotly using Team Viewer or something like that.

    Can you reproduce using the zero demo project? The main problem is that redis has nothing to do with other components.

    I am not sure. I have to spend some time doing that. I'll do it and let you know as soon as possible!

    Resolved. I added to redis connection string the parameter syncTimeout=10000.
