In man(5) unbound.conf it says this:

# make sure unbound can access entropy from inside the chroot.
# e.g. on linux the use these commands (on BSD, devfs(8) is used):
#      mount --bind -n /dev/random /etc/unbound/dev/random

I can see that you use a chroot. I'm wondering if you've not mounted a /dev/random into the chroot and maybe it's running out of free entropy for something and blocking. This might explain why it works for a while and then fails.

I do this:

In /etc/fstab:

devfs                   /usr/local/etc/unbound/dev      devfs   rw      0       0

In /etc/rc.conf:

devfs_set_rulesets="/usr/local/etc/unbound/dev=devfsrules_unbound"

In /etc/devfs.rules:

[devfsrules_unbound=10]
add hide
add path random unhide

Might help?
