Unbound randomly fails to resolve names

[RayG]

Hmmm,

 

Is no one else seeing this issue?

 

I have seen no replies from nlnetlabs or anyone else.

 

There must be a reason why things are failing?

 

Puzzle by the lack of response.

Hi,

 

After resolving my performance issues in the thread :

 

"Unbound can be made unresponsive when using DoT" in the June archives.

 

I now need to understand why Unbound randomly fails to resolve names and
causes various processes on my system to work incorrectly.

I hope the unbound users list allows attachments I have tried to add a zip
file GetRootHints.zip which contains all the data to cause the issue.

 

It contains a short PowerShell script just to obtain named.root from:

 

https://www.internic.net/domain/named.root 

 

Examples of what happens when it fails and also when it works.

 

The unbound log file for both working and failing - verbosity 4

 

I have also included the Unbound configuration file details

 

So if anyone can advise why things are going wrong and how to correct them
if indeed I can by changing the configuration.

 

It would also be useful to know if this example fails on other systems.

 

The zip file can also be found on MSOneDrive here:

Thanks

 

Ray
