Incredible paging on the system

Hello, We have a Delphi application that runs for more than an hour, the paging on the system is incredible!! After less than an hour the system "sits down"...... I'm not able to use the system anymore. Not even thake the engine off-line. The system is HP 9000 E35 with HP-UX 9.04 and Informix OnLine 7.12 UC3. This is an extrac of the onconfig file. Do I need to change something in order to avoid paging on the system? Or could it be the Delphi application?
