Today I filed a bug, which I should have filed almost one year ago. I saw it several times, I even had solution for it, but I didn’t think/know it was a bug. It was reported here: http://world.episerver.com/forum/developer-forum/Problems-and-bugs/Thread-Container/2016/9/commerce-catalog-randomly-goes-empty-until-website-restart/ and here http://world.episerver.com/forum/developer-forum/Episerver-Commerce/Thread-Container/2016/6/addstaticattributepropertyvalues-object-reference-exception/

If it does not, well, it can be anything else. But at least it’s not caused by certain things – the key is to narrow down the causes of problem. You can also try to call
