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) Kris --SUOF0GtieIMvvwua Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (FreeBSD) iD8DBQFB2zn/Wry0BWjoQKURAjh+AJ9xizBBsit5PNGHTFmfzKcCUYAblwCdHdXM 3W9PKeccFyOSdVUxgvn4W7A= =pEje -----END PGP SIGNATURE----- --SUOF0GtieIMvvwua--
