json not saving large amount of data to server

Question

Dear reader thanks for your consideration 

 Here I want to ask Question that i am drawing visio like diagrams by using HTML5 canvas by using fabricjs canvas liabrary.

I drag drop diagrams  and then save them into text file on server side. The problem is that i am unable to save the objects more than 114. means when i draw a diagram and save it it will be saved successfully but if i dran approx 50 diagrams it not saved. 

i am saving using json.

see the link below 

http://prntscr.com/f80dgn 

diagrams shown in the above link are saved successfully but when i try to save the data after adding just 1 more diagram it will not save.

the neccessary json code is here. 

 

selectAllObjects(true);

// deactive all the objects (means if some are selected/Highlited will we in normal/deselect mode).

canvas.deactivateAll().renderAll();

var jsonCanvas = canvas.toDatalessJSON();

//alert(jsonCanvas);

var jsonData = JSON.stringify(jsonCanvas);

// alert('Total canvas objects: ' + canvas.getObjects().length);

//alert(jsonData);

// debugger

// $("#savestus").show();

// $("#savestus").html(" Saving...");

$.ajax({

type: "POST",

url: "page2Fabric.aspx/saveJsonData",

data: '{jsondata: "' + encodeURIComponent(jsonData) + '" }', //e

contentType: "application/json; charset=utf-8",

dataType: "json",

success: OnSuccess,

error: OnError

});
