Hi all,

Who here knows about the scheduler mode? Whenever I set mine to Timer Mode, my portal won't start.

I've seen another thread talking about the same thign here, but no solution:
http://www.dotnetnuke.com/Community/Forums/tabid/795/forumid/107/threadid/198760/scope/posts/Default.aspx

I never worried about it in the past, but now I have a module that needs it and it has already knocked my portal out of action. The only way to get it back up is by resetting the option in the database.

What owuld cause timer mode to stop the system altogether? Any ideas are much appreciated.

Rob

I'm running 4.8.4/sql2005

I had exactly the same thing happen to my portal (4.8.4, SQL 2005 as well) the other day.  I only have 3 custom scheduled processes but each of them is optimized to work without an HttpContext (I followed the instructions of Joe Brinkman's blog from quite some time ago).

My thoughts are that it still *probably* has something to do with that -- something needs an HttpContext and fails miserably, but I really have no way of confirming because no errors are logged to the EventLog in DNN -or- on the server.

I disabled all of my custom scheduled processes and tried it and it still failed, so I'm certain it either has to do with the timer mode in general or one of the core scheduled processes.  Since it was our intranet, I didn't really feel like going through and enabling/disabling processes one by one until identifying the culprit.  My three processes run every 5 minutes, but they are more than fast enough to get their job done in the five minutes and not overlap a subsequent request.

Processes we have enabled:

DotNetNuke.Entities.Users.PurgeUsersOnline, DOTNETNUKE (every 1 hour, retry 5 minutes
DotNetNuke.Services.Scheduling.PurgeScheduleHistory, DOTNETNUKE (every 1 day
DotNetNuke.Services.Search.SearchEngineScheduler, DOTNETNUKE (every 1 day)
DotNetNuke.Services.FileSystem.SynchronizeFileSystem, DOTNETNUKE (every 1 day)
DotNetNuke.Services.Cache.PurgeCache, DOTNETNUKE (every 4 hours, retry 30 minutes)

I also see no errors. I've posted a screengrab of my log over here... the second from the top restart is the frozen one... no further exceptions until I got it reset to request mode.

We need someone with some knowledge about this area.... help!

Just bumping this to see if anybody has some input.  I would love to use the timer mode but so far have been stuck on using the request method.

Yes please keep it up here.. someone must surely have a grain of knowledge in the area.

I don't know if it's related, but I've been noting a fair few freeze-ups after making language file changes as well lately. I mention it because it also causes the site to just hang there until I reycle the pool, same as the other issue.
