A question about some mechanics

[Sarin]

So I've been messing around a server with many items greatly modified, including various additional "gain item when killing monster" items. I tried loading a character with as many such items as possible, and noticed that when I had too many, some of them stopped working. So, does anyone know specific mechanics detailing this?

I'm pretty sure it's a max of 10 added drops from items.

Is it even possible to get more with only official items?
