Hi Nukers,

Running DNN 7.1.2.  The scheduler on one of my sites is continually writing logs like this....

DotNetNuke.Framework.Reflection - DotNetNuke.Modules.Chat.ChatControllerSystem.Web.HttpException (0x80004005): Could not load type 'DotNetNuke.Modules.Chat.ChatController'.   at System.Web.Compilation.BuildManager.GetType(String typeName, Boolean throw , Boolean ignoreCase)   at DotNetNuke.Framework.Reflection.CreateType(String TypeName, String CacheKey, Boolean UseCache, Boolean IgnoreErrors)

Seems to be related to a "ChatController".  The thing is, I don't have any chat software installed (used to ages ago, but got uninstalled it).

This is causing the site to continually re-start.  Any ideas on why this is happening, and how to fix?

Thanks,

Rod

In Host > Scheduler, make sure there is no job remaining from previous Chat module install.

Thanks Sebastian.  I checked this, and there are no scheduler items for any sort of chat control.  Looking through the event log, I can see that DNN is enumerating (reflecting) a lot of the modules, and similar log files are created, just with a different name, so I don't think it's a specific module that's causing this.

I disabled all of the schedule items, and then after turning on any one of them I get SQL referential integrity issues when running any of the scheduled items.  This is weird, because the dbo.Schedule table is empty.  These RI errors are always followed by a corrupt memory error.

Is the scheduler as installable component of DNN?  Can I just re-install what seems to be a broken scheduler?

Thanks for any advice.

Rod

I've just upgraded to the latest 7.2.0, and this error is still occuring.

The error is occurring whenever the scheduler is enabled (either timer, or request). It doesn't matter which schedule events are on. Currently I've disable all of them except one. I've tried various schedules - all of them produce the same thing.

The referential integrity error is happening because it's trying to insert into tblScheduleHistory a value of 0 for the ScheduleID. I temporarily removed the RI constraint to determine this. After the record was inserted into this table, I could see that the StartDate, EndDate, Suceeded etc were NULL, indicating that the schedule failed (no surprise).

So basically, the scheduler is failing.

The problem is, how can I trouble-shoot this further? How can I find out why the scheduler is failing on ANY of the scheduled items?

Many thanks.
Rod

Does anyone know what the "DotNetNuke.DNNScheduler.dll" does? I found this .dll in the bin folder of the site that does not work. I compared the bin folder of another 7.2.0 installation and it does not have this dll, so I'm assuming it is not required? Perhaps a left-over from a previous version of DNN?
