Just want to chip in that I also experience the same issue. This is my
home firewall running squid/unbound/isc-bind/isc-dhcpd/pf/zfs.
Have a couple of tmpfs and NFSv4 mounts.
Was about to order new hardware since I thought it might be failing,
lol. Haven't had time to hook up a monitor/console, but generate some
load on the machine after a day or so of uptime and it feels as IO has
just stuck and a reboot is necessery. Actually managed to update it
yesterday, after a pre-reboot procedure.
I have noticed vfs.numvnodes constanly rising to maxvnodes, so I bump
that a bit.
