Reports & Discoverer :: REP-1800 - Formatter Error VGS-1701 - Not Enough Memory?

While running large report to screen the error is:

"REP-1800: Formatter error. VGS-1701: Not enough memory"

My Observation:When running report to screen, report builder creates 3 temporary files to REPORTS60TEMP folder. When one of the file size reaches to exactly 2GB it gives the above mentioned error and report crashes.

I have visited metalink and get the following:

Problem Description
-------------------
You are running a very large report to screen or preview and you get the following errors:

rep-1800 formatter error
vgs-1701 not enough memory

Solution Description

Increase the size of the buffer for the report.

i've tried following solutions but problem still there:

1) increase and decrease the size of the buffers
2) Removing total number of pages filed so all pages not formated at once.
3) increase the size of the virtual memory of OS
4) increase the size of the PC to 1 GB

I am using report builder 6i, Oracle 10g and windows XP
