If the vnode is in cache, the associated file data may be cached too,
depending on some other system settings.
This means that besides the memory needed to hold vnode structures,
additional memory is used.
What is you vm.filemax setting? I have settings like this:
> sysctl vm
vm.loadavg: 7.39 6.77 6.46
vm.nkmempages = 32768
vm.anonmin = 10
vm.execmin = 5
vm.filemin = 10
vm.maxslp = 20
vm.uspace = 16384
vm.anonmax = 80
vm.execmax = 30
vm.filemax = 50
I guess that setting vm.filemax to lower value that what
you currently have might help you.

Yep. Perhaps send-pr the problem so that someone would address
