1. Some more info about the version would be welcome. I know some versions prior to DNN 9 could have issues that sound like this.
2. As it happens around 12.00, I would lead me to check the scheduler. Every scheduled task can also be run on demand, so you can try to create the 500 error on the spot. And then check the Admig log to see if there is any pointer.
Running through the scheduled tasks, it appears Purge Client Dependency Files scheduled task may be the culprit. It created the 500 error when I ran it manually. Thank you for helping me identify that. Any suggestions on next steps?
