In current there is little you can do. Setting kern.maxvnodes has no effect unless debug.wantvnodes is set to 0. Setting debug.wantvnodes to 0 just gives kern.maxvnodes the old function of debug.wantvnodes. Setting debug.wantvnodes has very little effect. It just controls how fast the system ramps up to peak vnode allocation. This is bogus of course. The man page is more bogus/incomplete. Bruce
