[Unbound-users] sendto failed: Operation not permitted at 3am?

[donotreply at projectumbra.com]

Hi - Apologies if this is old, tried google but couldn't find something
that seemed to answer.

Recently upgraded to freebsd 10.0 and switched to unbound.  Everything
seemed ok.  That was about a week ago.   However, I've just noticed in
my log files a significant # of sendto failed: Operation not permitted

What is quite odd is:

This happens everyday at 3AM local time
It happens with 5 IP addresses
The 5 ips all belong to Dell.


Of further note, neither the server or anything on the local net has any
Dell components or assessories.


Thoughts?

Thanks!
