It's a typo, should be: root@eris samba3 # sysctl -a|grep kva kern.ipc.maxpipekva: 8359936 kern.ipc.maxpipekvawired: 4177920 kern.ipc.pipekva: 262144 kern.ipc.pipekvawired: 0 vfs.buffreekvacnt: 0 - when I had this a oouple of weeks back (on 5.2 release) it was because I'd borked my make.conf so I effectively forkbombed the box everytime I tri= ed to build a port ....
