Hi,all I ran a program under FreeBSD 4.11.I have 1G RAM and I set the SWAP to 3G(I only have one partition). But the system gave an error msg "Unable to alloc xxx bytes" during the running. And I noticed that when the Swap usage was only 1%. Shouldn''t the whole SWAP be used as the virtual memory? Or do I need any extra setting to do so? I will really appreciate it if anyone can help. Thanks a lot. Cheers Longbo Huang
