A setting change is required in ColdFusion Administrator to increase the default document setting to a larger size. Your company Web Administrator must log into ColdFusion administrator and Click on Settings, under the section titled Request Size Limits ensure the fields read as follows: 

Maximum number of POST request parameters 500 
Maximum size of post data 105 MB *
Request Throttle Threshold 4 MB *
Request Throttle Memory 200 MB*

*These values are for a 105 MB upload size limit.
