    Hi there, 
    On this DNN 8.0.4 site, which has a lot of users, sometimes the site gives an error.
    After clearing the cache, or recycling the app pool the error is gone.
    When we look in the log, we see a lot of repetitions of the same error which probably cause the problems.
    So they look like this:

     at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
       at DotNetNuke.Entities.Users.UserController.GetCachedUser(Int32 portalId, String username)
       at DotNetNuke.HttpModules.Membership.MembershipModule.AuthenticateRequest(HttpContextBase context, Boolean allowUnknownExtensions)
       at DotNetNuke.HttpModules.Membership.MembershipModule.OnAuthenticateRequest(Object sender, EventArgs e)
       at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
       at System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step)
       at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)
     

    Apparently, this is some kind of caching issue. So what might cause this to happen and how can we make sure the cache is up to date

      Check the /portals/_default/logs directory, and look at the latest log.resources file.

      Hopefully there is more information in there to help diagnose the issue.
