That doesn't seem to be pointing to an mbuf leak (I don't know if it
would have the same failure mode anyway).

The following sysctls should be relevant (your values will of course
be much less):
=20
vm.kvm_free: 264237056
vm.kvm_size: 1069543424
vm.kmem_size_max: 419430400
vm.kmem_size: 419430400

If you're sure this is a smbfs problem, then we should change the PR
title so that a future smbfs maintainer will notice it (smbfs is
effectively unmaintained in freebsd thesedays)
