JSON data limit to coldfusion Server from JQuery Ajax call

[Guest]

We have been using coldfusion 10 Server and developing applications with YUI tables, JQuery And Coldfusion components.  We have been facing issues when we try to submit a big chunk of Json data to coldfusion cfc component function.  This brings the coldfusion service down.  This really sucks and we have no solution for this yet.  This happens even when the form is submitted with a big chunk of JSON data.  Coldfusion unable to handle this data and hit the service and bring the coldfusion Administrator down.   Below is the sample data sent from the client to server through ajax call.  cfc component receives this data but unable to handle this chunk.  I believe there is no limit for the data being sent from Ajax but when this is received in the cfc function this hits the service.  Any help would be much appreciated?
