Abnormal termination of Forms 6i

Hi,
My application constantly crashes.
I have an application developed in Forms6i (Rel. 6.0.8.0.8) on Windows 2000 DataCenter/Adv server, backend is Oracle8i/9i. We use 20-30 tables and 20 fmx files, 16 pll files. It doesn't have any errors.

If we are playing around the application it crashes.else it runs fine, or if u make continious transactions in the application, it crashes in middle. It says it is a memory problem in a dump file. how can i solve this. It is said that it is the main drawback of Developer6i (Du to oracle form 6i Memory Leak). So According to Oracle this BUG was been fixed in Patch 7/9, but after installing it NOTHING HAPPPEND (It still dose that).
I regenerated all Modules( From Designer 6i) and the recompiled all the the forms(From Developer 6i) and it didn't help.
