Json body truncated by the 'write' operation

[alephteam]

Good morning,
I'm using the last release 1.9.5 of the library.
I prepare the body of the Json::Value and then I make the serialization using a 'StyledWriter' calling the 'write' method, sending the output via HTTP.
Usually it works perfectly but when one of the items of the body is very large (*). In this case the body is truncated and so uncompleted.
Is there a limit in the size of the Json::Value passed to the 'write' method?

Thank you.

(*) I use to send a preview of a .bmp image converted to Base64 format. When the image is larger than usual I detect the problem.
