I could not reproduce, please let me know what link property values you are using -

Code
Select All
var node1 = diagram.Factory.CreateShapeNode(10, 10, 100, 100);
var node2 = diagram.Factory.CreateShapeNode(210, 10, 100, 100);
var node3 = diagram.Factory.CreateShapeNode(10, 210, 100, 100);
var l = diagram.Factory.CreateDiagramLink(node1, node2);
l.Text = "test";
l.Origin = node3;

Ok Agreed.

In below code it will not come .
Can you please check your source code ?
Is there any possibility ?
Why because stack trace clearly says about the code methods also.
can you please check with your developers to reproduce this bug.
Even I will try to create a simple sample code from my end if possible.
But please note our application is very large. May be, the problem or we are assigning some wrong value to the property. But we have checked in our end and its not. Then I suspect based on our value u might be giving that margin. Any way , you can control these scenarios in your source code.
Please try to find the bug.

Thanks in Advance.

Yes, what I asked was for you to copy your link property values to sample code above until you get the exception. We've checked our code but cannot imagine how it will create an auto,auto,0,0 margin, unless the nodes have some strange coordinates too (e.g. NaN), so maybe also try assigning your node coordinates from time of exception to the test nodes above.
