You might investigate the postParametersLimit and postSizeLimit values in your server's neo-runtime.xml file. I suspect you'll need to increase the values for those two settings. Remember to back up this file before making any changes. You will need to restart the CF server to apply any changes made to the settings in this file.
See the CF 9.0.2 release notes for more information: http://helpx.adobe.com/coldfusion/release-note/coldfusion-9-0-update-2 .html
To clarify. I would increase the postParametersLimit value to handle a larger number of form fields. I would increase the postSizeLimit to handle large form submissions, such as when uploading (posting) files from client to server.
