My loader.conf has kern.maxswzone=4200000 and ccache is fully active and working for both root on tcsh and users on sh. I have yet to try synth again. I'm doing buildworld/buildkernel for 12-STABLE, but evidence so far is good. 'top -t' is actually happy, showing 16G (grog?), so I'll try firing up synth after another hour or so on the latest fetch of the ports tree. Happy coder, me! :D -- Don Wilde **************************************************** * What is the Internet of Things but a system * * of systems including humans? * **************************************************** [-- Attachment #2 --] # Device Mountpoint FStype Options Dump Pass# /dev/ada0s1a / ufs rw 1 1 /dev/ada0s1b none swap sw 0 0 /dev/ada0s1d /exp ufs rw 2 2 fdesc /dev/fd fdescfs rw 0 0 proc /proc procfs rw 0 0help
