I have a website that I have run for years running a custom built CMS. It has had no problems ever. I decided to create a demo (temporary url) of the CMS using the exact same website. Only people I give access to would be able to login and change it, so it basically is not in use for the most part.
I tried this demo site the past few days, and I noticed that I kept getting System.OutOfMemoryException errors. I would wait for an hour or so, then it would work. Next day, same thing.
What could explain this? 2 exact same websites....one that is used all the time (no memory issues), and one that is hardly ever used (memory issues). Doesn't really make sense to me.
