I have half a dozen NopCommerce instances on my VPS ranging from version 2.65 through 3.7. The memory use for one, in particular, climbs over 1.5GB steadily after an application pool recycle, while the other 3.7 stores hover around ~200K. It doesn't even have that many products and a relatively small db. I've checked the one simple plugin I have... Is there any way to determine what is causing this? Any most likely settings to check?
