Hi all. Not sure if this is the right place to post. On a fresh install of PiHole and unbound, I noted that the unbound service keeps stopping and starting, each time flushing its cache and making all forward requests to unbound take a few 100ms. I have set up unbound to serve expired entries (whils…

Not sure if it fits here, maybe a unboud forum would be the better choise?

Please post the output of the following command - this will show the non-commented lines in the unbound configuration files: sudo grep -v '#\|^$' -R /etc/unbound/unbound.conf*

/etc/unbound/unbound.conf:include: "/etc/unbound/unbound.conf.d/*.conf" /etc/unbound/unbound.conf.d/root-auto-trust-anchor-file.conf:server: /etc/unbound/unbound.conf.d/root-auto-trust-anchor-file.conf: auto-trust-anchor-file: "/var/lib/unbound/root.key" /etc/unbound/unbound.conf.d/qname-minimisa…

[image] doncarajo: I have set up unbound to serve expired entries (whilst fetching an updated record for the next time) which has worked well before and minimises lookup times. What performance problem were you experiencing that led to using this option?

Only a slight delay on loading pages. When TTLs expire, PiHole forwards the request to unbound. Because unbound keeps restarting it doesn’t have any useful cache to serve from, so queries can take from 100ms to over a second (depending on where the servers are I suppose). When it’s not resetting con…

I would temporarily increase the unbound logging verbosity to 5 and see if there is any indication in the log for the cause of the crash or any common factors. You have set fairly high memory settings as well - the default for both of these is 4M: msg-cache-size: 128m rrset-cache-size: 256m You m…

This thread ( Frequent unbound restarts | Netgate Forum ) seems to be related to the issue I've encountered. This on pfSense though, so I'm not sure what the workaround would be in PiHole. Edit: I suspect a custom settings file in /etc/dnsmasq.d needs to be created but I don't currently know which se…
