CFGrid error when input too long

Hello,

We have a grid that is bound to fields in search criteria form to filter the grid results.  The actual screen has 10 search fields, but the basic code looks like this:

<cfgrid name="gridReports" format="html" bindOnLoad="false" selectOnLoad="true"

       bind="cfc:getReports({cfgridpage}, {cfgridpagesize}, {cfgridsortcolumn}, {cfgridsortdirection}, {form:field1@none}, {form:field2@none}, {form:field3@none} )">

               <cfgridcolumn name="column1" header="Column Name" >

               <cfgridcolumn name="column2" header="Column Name" >

               <cfgridcolumn name="column3" header="Column Name" >

We have this running in 2 matching environments.  In one environment, this runs without any problems.  However in the other, when you fill in many serach fields or enter some long text into a few, it will return " Error invoking CFC [cfc filename]: Not Acceptable."  If you limit the search values entered, then the search runs just fine.  Any ideas on what may be causing the error and/or why it is only happening in one environment?

Thanks for your help.
