Hi,


sysctl program. This is somewhat unexpected...

sysctl kern.maxvnodes=1048576000 results in 100% CPU and a non-killable

fixed here https://cgit.freebsd.org/src/commit/?id=32988c1499f8698b41e15ed40a46d271e757bba3

I confirm.

There may be dragons...:
kern.maxvnodes: 1048576000
vfs.wantfreevnodes: 262144000
vfs.freevnodes: 0              <-----------------------
vfs.vnodes_created: 11832359
vfs.numvnodes: 146699
vfs.recycles_free: 4700765
vfs.recycles: 0
vfs.vnode_alloc_sleeps: 0



Bye,
Alexander.

Another time I got an insanely huge amount of free vnodes (more than maxvnodes).
