Does anybody out there know why Online 7.1 reserves 99% of swap space on our HP9000/K400 running HPUX 10.01. We have 640 mb of ram and over 600 mb of swap. The shmax parameter is set to it's highest setting possible. I don't have my notes with me, but it is something like 0x4000000. This swap reservation causes other processes not to be able to start. Buffers in informix are set to 60,000. This was 100,000 but had to be reduces to start other processes. This seems to be the only informix parameter that affects this swap reservation.
