I have been getting acouple of errors on a new install of DNN 4.08.04.  I have found multiple threads about the but but no fixes (that work) and the threads all just stop sometime in May.

I get this one from  DotNetNuke.Entities.Tabs.TabController.FillTabInfo

I also get a similar null ref error from DotNetNuke.Entities.Modules.ModuleController.GetModuleByDefinition

System.Exception: Unhandled Error: ---> System.NullReferenceException: Object reference not set to an instance of an object. at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add) at DotNetNuke.Entities.Modules.ModuleController.GetModuleByDefinition(Int32 PortalId, String FriendlyName) at DotNetNuke.Entities.Portals.PortalSettings.GetSiteSetting(Int32 PortalId, String SettingName) at DotNetNuke.HttpModules.UrlRewriteModule.OnBeginRequest(Object s, EventArgs e) at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) --- End of inner exception stack trace ---

I get these error from 3 to 10 time daily on a low trffic site (high percent of users that see errors).  I had high hopes that this was fixed after seeing the problem discused at the end of '07.

This doesn't help me defend DNN as a platform to my dev team.

Please Help

I'm afraid I cannot help you a lot but I can tell you this, I run multiple versions of DNN for multiple sites with SQL 2000 and 2005 on my server and I have never seen that error.  I am not familiar with the history you mention either but, I don't think PortalID should be -1.  Also, that method name with "Dictionary`2" looks kind of funky.

You've probably been over all the basics but just in case, how are your server resources?  Memory?  Is SQL Server on the same box?  How's the memory for it?  Available disk space?  How about the Windows system logs, do they show anything strange?  Does it happen with any browser?  Do you have all the latest patches?  What if you add the site to the "Trusted Zone" in the browser?

Tell your dev team to hang in there, this is not a widespread issue in my opinion.  Just wanted you to think out of the box for diagnostics, in this case the box is DNN, look into the O/S, server, and infrastructure health to see if there's anything that may be producing intermittent problems.

 We are in final prep stage on 4.9.0 and expect to release it early next week.
