Hi Sebastian,

We have the following modules installed: Active Forums, Active Forums What's New, Active Social, ActiveForumViewer, Authentication, Banners, Blog, BulkUser Manager 2, Console, ContentList, Dashboard, Documents, Engage: Tell A Friend, Events, Extensions, Feed Explorer, Feedback, File Manager, Google Analytics, Host Settings, HTML, Languages, Lists, Log Viewer, Marketplace, Messaging, News Feeds (RSS), Newsletters, Portals, Recycle Bin, Scheduler, Search Admin, Search Input, Search Results, Site Log, Site Wizard, Sitemap, Skin Designer, Skins, Solutions, SQL, Survey, Tabs, Taxonomy Manager, Tell-A-Friend, Users and Roles, Vendors, ViewProfile, Whats New, XML/XSL

I have submitted a support ticket to our hosting provider to check on the logging for IIS App Pool recycle events.

SQL is on a separate machine.

Hi George,

Not running MSSQL Express but rather SQL on a separate server.

I will ask our hosting company to confirm the size of our application pool and the timeout interval. I would imagine these are simply set to default.

Host settings

You can see from the post above which modules we are running. All standard DNN modules apart from Active Social, Active Forum, Bulk user manager and the “tell-a-friend” modules.

At the moment the site has over 600 registered users. Problem still occurs in the middle of the night when we have no visitors.

The site does not break... it simply runs slow (as if it has been restarted) every 6 minutes. Surely something must be showing up in our hosting companys IIS logs?

Hi Richard,

We have only noticed the problem in the last week. In this time the only things that have changed on the site have been:

New Site Log reports: http://www.ifinity.com.au/Products/Site_Log_Reports
And changes to the host settings: http://www.mitchelsellers.com/blogs/articletype/articleview/articleid/283/how-i-get-my-dotnetnuke-sites-to-run-so-fast.aspx

Here are the host settings:

Check For Upgrades: disabled
Page State Persistence: Page
Module Cache Provider: Memory (have tried file with no success)
Cache Setting: Heavy
Authenticated Cacheability: ServerAndNoCache
Compression Setting: No Compression
Use Whitespace Filter: Enabled
Site Log Buffer : 1 item
Site Log History: 0 days
Users Online Time: 40 minutes
Auto-Unlock Accounts After: 10 minutes
Scheduler Mode: Timer Method
Enable Event Log Buffer: Enabled
Auto-Sync File System: Enabled

Apart from that I cannot think of anything else which has been installed or added to the site, and I’m not sure any of those changes should have caused this recurring issue.

Unfortunately I’m not able to give much more information about the memory issue as I am still trying to get that from our hosting company. They were saying that memory usage was up around 80% but in what context I’m just not sure. Another thing they have said to me on the phone was that while they were looking at the server data memory useage went up y 30mb when I submitted a login, does that help?

Nothing else is sharing the server. It’s one installation of DNN, running one portal. SQL is on a totally separate server.

My big question is, surely there must be something in the server event viewer? The fact that I have tracked this problem client side (using a pencil, a clock and simply loging in and out) and found it’s slow every 7 minutes must mean there is an event of some kind happening server side, like an application pool reset, memory dump to paging file or something??

Thanks for any help!!
