The app pool on my DNN installation has to be recycled relatively often (every few days) when the site completely stops responding. Once the pool is recycled, the site kicks right back in. What could be causing this? I haven't modified any backend code.

Watching the IIS processes, the site is using a LOT of RAM. I made sure the app is caching to disk not RAM, and lowered caching to Low. What could be causing my DNN to use so much memory?

Thanks,

Robert

It often caused by third party moldule's memory leak, you can verify third party modules you used and do some tesing such as uninstalling some modules.

The web garden is not supported by DNN. You should not be using this feature. It will cause all sorts of issues, especially caching.

Are you getting errors in the Event Log? Can you post some of those if so? How about your Windows Application or System logs, anything out of the ordinary there?

Your AppPool, is it the default AppPool? Permissions set correctly? Is this the only web app on the server?Have you removed any un-necessary jobs from the scheduler? Are you using any type of HTML compression or white-space removal?

I could go on forever, but let's start with those.
