Maintaining State with OAS 4.8 and PL/SQL

Question

Hi,
I am working on a package that displays 5 pages with 83 application questions. To maintain state for all 83 questions, I am using a procedure that maintains the data on a string (~400 characters) and passes it to each page (We decided to avoid writing to the database before the application is completed). Since the pages were expiring randomly, I added NEXT and PREVIOUS buttons. One procedure, the one that maintains the string, has 83 parameters.
The package contains 8-10 procedures, 180 constants and global variables (we tried without using global variables but global variables make the code easier to read and the package smaller (around 4000 lines). The complete application uses 4 packages.
During development, the package seemed to be working well, until I added more realistic data. Right now, I get The error message: The page cannot be found. The first time, I got this message, just by pressing enter again will cause the page to display. At times it will take 3 or 4 times pressing the enter key on the URL. Slowly, it became more and more difficult to make the browser display the first page. Today, no matter how many times I press the enter key, the page does not display.
Questions:
1. Are there any limits on parameters, global variables and data on OAS 4.08. I tested reducing the package parameters, global variables and data to half the size, but the procedure still does not display. Compiling an older copy of the procedure does not seem to work either.
2. Is there a better way to maintain state without writing to the database?
I am not sure what is causing the problem. I have an open TAR.

ok some code example:
Let's gues you want to display 2 collums of the view all_tables
in html format:
First create a procedure with a editor (i use to do so).
create or replace procedure get_html (owner_in in varchar2) as
var1 number(12,0);
var2 varchar2(100);
begin
dbms_output.putline('<table>');
for fr_rec in (
select table_name, owner
from all_tables
where owner like '%'
