Missing post parameters when requesting tables with a huge amount of column by server-side processin

First of all, thank you for the great work done here.
I use the service-side processing of DataTables. My implementation is actually quite simple (see below) and it works fine in most cases, but for tables with more than 1600 columns the parameters (start, length, draw,...) are not transferred to the server. The function on the server is called correctly, but the parameter list is empty. Now my question is: Is there a limit to the maximum number of columns a table can have, because I have to display tables up to 3500 columns.

Cheers,
Ronny

$('#lazyLoadFinalMatrix').DataTable({
processing : true, ordering : false,
scrollX : true, serverSide : true,
ajax : { url : 'getMatrixAsync/final',
type : 'POST' }
});
