I've had problems with the scheduled task used to run the Search Engine Scheduler (e.g., DotNetNuke.Services.Search.SearchEngineScheduler, DOTNETNUKE)

Having it running as a scheduled task seemed to be causing performance issues and it seemed like it had a memory leak when another member of my team was reviewing it .  Is anyone else experiencing similar results? 

We turned the task off for the last 4 months and the performance issues we had haven't occurred since.  However, we have customers that want to use this feature, so I'm researching a solution and considering turning it back on. On my test server I'm seeing performance degradation again since the task has been turned back on and it isn't completing successfully.  

Is there a manual stored procedure that I can run in order to get this feature working again? Any ideas or information on this would be helpful.

Thanks in Advance!

The search engine schedule is not very good in my opinion.. It takes a long time, and you need to be very careful to get its settings correct..  The bigger your site, the longer it takes.   If it starts taking longer than the retry interval, then you will have problems.

The first thing to do is change the scheduler to use Timer Method (host settings page).. this at least gives the schedule a separate thread and improves the performance..

I have worked with many clients to get the performance of this in check without actual modifications to the code.

As the person above mentioned I would be sure that your scheduled tasks are running in Timer Mode.

Also, from the sounds of it you have a big site, set the interval on the task to be 24 hours, that way it only goes once per day, you still get updates but it will be better.  Then after it has ran have a look at the history to see the total execution time, and then you can tweak the run time accordingly.  If you need more details, feel free to drop me a message as we help clients with this type of issue all the time msellers@iowacomputergurus.com

We are having some of the same problems with the scheduler and the SearchEngineScheduler. We have the scheduler set to Timer mode. We also have our DNN sites split out amongst 4 or 5 applications pools in IIS 6. Does this mean that a scheduler thread will be started for each app pool? The reason i ask is that when i look at the history of the SearchEngineScheduler, it looks like the scheduled item is running numerous times. We the SearchEngineScheduler set to run once a day with no catch up or retry interval. For example, this is from the SearchEngineScheduler history from last night. Also, before these that i pasted below, there were 25-30 failed attempts. Thanks!

If all those App Pools are pointing at the same DNN Install then the answer is yes.

You don't want to have more than one asp.net worker process pointing at a single DNN installation or you will have this problem.
