hi all, I am having exchange 2000 server with P-IV, 512 MB RAM and Single Partition. My exchange server gives me error "your system is running low on virtual memory. the system is adjusting the virtual memory size". i observe the task manager, the Performance tab shows PF Usage very high. This type of behaviour is happening all the time. when i restart the E2k Machine. The PF Usage will be normal but as the days pass, the PF Usage will go on increasing and one good day my E2k will stop services. i need to restart the server again. This is quite irritating for me. Any advice/solution ????
