It occurs on r292895 and later.

Apache, Cyrus IMAPd, BIND and mpd5.  However, traffic is almost
nothing without running the periodic daily scripts.

I could not get it.

The following is usual case:

kern.maxvnodes: 400000
kern.minvnodes: 100000
Syncing disks, vnodes remaining...0 0 0 0 0 done
Syncing disks, vnodes remaining...0 0 0 0 0 0 done
vm.stats.vm.v_vnodepgsout: 129
vm.stats.vm.v_vnodepgsin: 836656
vm.stats.vm.v_vnodeout: 101
vm.stats.vm.v_vnodein: 90562
vfs.freevnodes: 39680
vfs.wantfreevnodes: 100000
vfs.vnodes_created: 141735
vfs.numvnodes: 59118
debug.sizeof.vnode: 472
