Just wondering if anyone else is experiencing their DNN 9 sites causing 100% CPU usage.  Have had my server choke up a few times recently. I have a mix of DNN 9 and DNN 8 sites on the server but it seems to be the DNN 9 sites (3 different ones) that are running away with the CPU usage.

I doubt that DNN itself is causing this unless the server has very low resources. I'd instead take a look at the third-party and/or custom extensions that might be in use. Also, it may be a good idea to run a virus scan on the server to see if anything is infected.

Speaking of virus scan... Some antivirus tools can actually be the cause of this on web servers that run dynamic applications like DNN.

Also, it may be worth looking at the DNN event log to see if there are any exceptions that may be contributing to the issue.

Also worth checking if it is w3wp.exe that is consuming the CPU or if perhaps it is SQL Server. If the latter, an SQL trace could shed light on what is causing the problem. Also worth trying to figure out if you can identify a specific action that you (or some user) is taking in the affected sites to trigger the issue, as that will narrow down the possible causes.
