All three must add up to less than about 2.75GB. Those parameters control the maximum virtual size of each process and have nothing to do with the amount of RAM in the machine. The kernel takes the top 1GB of virtual address space. -DG David Greenman Co-founder, The FreeBSD Project - http://www.freebsd.org President, TeraSolutions, Inc. - http://www.terasolutions.com President, Download Technologies, Inc. - http://www.downloadtech.com Pave the road of life with opportunities.
