I have a DNN site going live next week and I am trying to understand a large number of error messages in the Event Log. In order to try to reduce the number, I have disabled all the Scheduled Jobs - but I don't know what they all do and therefore how critical they are.  Is there any documentation as to the purpose of each job (I mean the "built-in" or "standard" jobs) and how critical they are to the proper operation of the site. Obviously turning of the "Search Crawler" means the search index goes out of date, but I am running that manually once a day.

The other jobs that were enabled are:

Purge Module Cache

Messaging Dispatch

Newsfeeds Background Loader

DNN Feedback

Thanks in advance.

Thank you - that does help, although the fact that it is 4 years out of date is a bit of a problem!

Is there really no up-to-date information on each job?

This is one of the big frustrations I find using DNN, having come to it recently.  The documents you find are either way out of date or assume you have been using DNN since day 1 and have no need to have the basics explained.

It's somewhat of a problem of DNN's history - opensource projects often have missing documentation as developers/designers prefer to work on new exciting things rather than "boring" documentation. However with DNN Corp being formed this has got better (the wiki alone has ~400 pages of often detailed content)

I wasn't able to find a good wiki page for this item, so created a page at  and copied in Mitchel's text (I'm sure he wont mind), update it and added some additional content of my own -the page can be found at (I will tidy up the formatting after lunch).

Note: both "Newsfeeds Background Loader" and " DNN Feedback" are scheduled tasks by 3rd party modules so I don't have details of what they do.

Thank you - that is very helpful and I hadn't realised that two of the jobs were third party modules - which I have actually already uninstalled! That may clear up some things too.
