I remember reading an article on mulch a long time ago that talked about the buildup of amonia as mulch composts itself. The heat causes this to occur. The article went on to say that mulch develops this problem occasionally when it has been heated a great deal (center of pile like somone else said) and the amonia build up can kill plants. It said the mulch gets somewhat sticky and can stain sides of houses and to be careful.
Now I have personally never seen this staining or plant killing. I have caught a whiff of decomposition in wet hot mulch but that is the extent. So, that is my 2 cents.
Good luck.
