 1. The input is not a valid JSON
 2. The `StaticJsonBuffer` is too small
-3. The `DynamicJsonBuffer` fails to allocate memory
+3. The `StaticJsonBuffer` is too big (stack overflow)
+4. The `DynamicJsonBuffer` fails to allocate memory
 
-If you're is case 2., you can solve the problem by increasing the size of the `StaticJsonBuffer`or by switching to a `DynamicJsonBuffer`.
+Case 1. seems obvious, but a lot of issues are caused by from an invalid input.
+In particular, if you're writing an HTTP client, you need to skip the HTTP headers and send only the JSON payload to ArduinoJson.

-If you're in case 3., you may have a memory leak, it up to you to find it. You can try to switch to `StaticJsonBuffer` which is more efficient.

+If you're in case 3., you can try to switch to a `DynamicJsonBuffer`. Indeed, most platforms have a fixed size of the stack (usually 4KB on the ESP8266) the rest of the RAM being reserved to the heap. That's why moving the `JsonBuffer` from the stack to the heap can solve this kind of problem.

 Also, if the input string is constant, the `JsonBuffer` will have to make a copy of it.

 To avoid any duplication, make sure you use an input of type `char*` or `char[]`

 ### The first parsing succeeds, why does the next ones fail?
