Hi Rob,

Unfortunately, as soon as I remove the 'forwarders' in any of my named servers, the problem comes back. The output in my previous message was captured just a few minutes ago after I had disabled 'forwaders' in one of my bind servers.

Regards,

Vincent

I strongly suspect that this was caused (even if indirectly?) by the MASSIVE 
and many-hours-long power outages in Europe, mainly in Spain and Portugal. That 
started on April 28,
2025, at approximately 6:33 a.m. Eastern Time (ET) - and the majority of it 
lasted almot 24 hours.

Hopefully, you're not seeing any more of these errors now?
