After investigating the issue I have found that it is a ASP.NET limitation put in place in order to prevent DOS attacks on web servers.
The maximum request size in kilobytes. The default size is 4096 KB (4 MB).
In order to bypass this limit you need to :
1.Open the Web.config file located in <Perfectforms Folder>/services/Web.config with a text editor
2.Add the following key under the <system.web> tag:
<httpRuntime executionTimeout=”YourNewTimeInSeconds” maxRequestLength=”YourNewFileSizeLimitInKBs” />
4.Restart the Perfectforms application via IIS management console.
executionTimeout is not required but would be useful because large uploads might timeout.
maxRequestLength’s maximum value is 2097150
