Hello guys,
I am constantly getting the following erros in my dotnetnuke event viewer

Most frequently the failed schedules seem to be:

Search Engine Schedular
Purge Schedule History

Once in a while PurgeSiteLog errors out and it has done so more than once but I don't get as many schedule errors on this as I do on the two above.  So my question is first what could be causing these scheduled tasks not to be able to fulfill what they were set out to do correctly.

Secondly could the constant flood of these dumped scheduled failers cause for a memory consumption of a dotnetnuke installation to go out of control.

While I'm on the event log erros I will give you a couple other errors I am constantly getting via my dotnetnuke portal and see if you could give me some direction in these as well.

Other alerts I have been receiving as of late are these general exceptions like the following:

These are just some of the different kinds of errors I am still receiving and am wondering if you have any idea of the kinds of things that could be causing all these errors to be thrown.

Would you suggest that I start by turning off the automatically scheduled events of those things that are continually failing or is their some way of easily getting to the bottom of continually failing scheduled tasks.

Lastly would turning off tasks that keep failing save on memory and perhaps allow the web app not to consume so much memory thanks

Bo

Was there an answer on this?

My DNN just went belly up because of the Scheduler. I'm getting the exact same kinds of errors as Bo is getting. I had to turn Scheduler off in order for my site to respond as it should.

Help would be MOST appreciated.

Thanks,

Mark

Actually, this is the error I keep getting over and over, like every 10th of a second:

When I put my scheduler on Request Method or Timer, the site slows to a stop and takes, literally, forever to get a page up and running.

Thanks,

Mark

Did this just start happening, or has this always happened?

Check your database, truncate the event file, etc.

Mark,

Did you find the culprit? - The usual method is to turn off all scheduled items and then re-enable them one at a time to find the problem. - the main one I have found this to be is the search engine Scheduler, I have had to disable it as it was causing cpu maxing problems among others.

Cheers,

Hi All,

I figured out what the problem was (well thanks to outside help! I ain't that smart!)

The culprit is the timing of the Search Engine Indexer in the scheduler. The thing is, you have to
change the values. When DNN was initially setup, it came with a preset of Indexing every 30 minutes.
The problem is that when you have more and more content, it takes longer to perform the indexing,
so it gets to the 30 minute timeframe and then starts to reindex, even though the other index never
finished, so it throws error after error.

I had to stop the indexing, change the values, restart the Application and then startup the scheduler.

I changed the index to a 6 hour timeframe. My content won't show up so quickly on internal searches,
but at least it won't go into spasms anymore. This answer was actually provided by Mitch Sellers who
I contacted. I'm in the process of signing a contract to have him on retainer to help in the future. Well
worth the oney in my opinion to have someone who really knows what's going on.

Cheers all!

p.s. Joe, do you have anything for me yet? :-)
