Probably not, but it depends on your workload. If you never ran out of swap with 512MB, you probably won't with 2GB either. You'll also want to enable mini crashdumps (add "debug.minidump=1" to /etc/sysctl.conf), since if the system panics, it won't be able to dump 2GB of RAM into 1GB of swap :) -- Dan Nelson dnelson@allantgroup.com
