CF10 Truncating String

We have a Coldfusion 10 Application that is calling a .NET Class Library (Framework 4.0) which exposes a Base64 String as a Property. On the Coldfusion end, we are converting the Base64 string to PDF and it is being rendered to the users. The issue we are noticing is that the Coldfusion is getting a partial / truncated Base64 string.

We have created a test ASP.NET application that mimics the same behaviour of the Coldfusion application and we are getting the complete Base64 string without truncation. Also, the same Coldfusion application works on other internal Webserver without any truncation. Are we missing some setting?
