I have created a simple application at my company. It presents a single page with a table of cached installers that people need, updating local cache as necessary.

If I clear the cache on the server side, and visit the page after the first couple of files are cached I start to see "Single item size exceeds maxSize" on the server console.

At the point, I do not know:
- Is this related to the total downloaded amount on the server size?
- Is this only happening on the later downloades because they're the larger ones and the smaller ones don't trigger it because they're under a threshold for single items downloading?
- What actually triggers this message?

I have put the phrase in to the search engines, but if it has told me the right answer then I haven't understood it.

I would like to know how I go about figuring out the cause here, and pointers to documentation or someone else's write are just fine. The issue is almost certainly me not knowing something that is assumed, due to my lack of experience.
