Unbound frequently restarts on 2.2 - is this normal?
-
I have the same problem with unbound. There seems to be a direct connection between unbound stopping and restarting and DHCP leases. At 8:56:11 the unbound service stopped and then restarted:

At that exact time i get this in DHCP logs:

Do you have a cron job rc.backup_dhcpleases.sh that is running every hour?
It must be over-enthusiastic and restart unbound when the lease file is written. Perhaps it can just send unbound a message? Or perhaps it does not need to tell unbound anything - unbound should already be getting DHCP lease data on-the-fly as it happens?
-
Nope…
$ crontab -l
crontab: no crontab for root -
crontab -l
That does not work for me either.
cat /etc/crontab
and see what is there.
Or instal the Cron package and you an see the cron jobs in the webGUI. -

If you do so, this file must be terminated with a blank line (e.g. new line)

I am going to have to assume this is the intended behaviour at this point. It doesn't cause any adverse effects for me.
I do have the OpenVPN client configured (in case this is somehow interacting with unbound) but it is constantly connected and not restarting.
Would be nice to get confirmation from one of the developers though…
-
No - Its not intentional (Unless mine is broken. Unbound has been running without service restart for a week)
-
While troubleshooting another issue, I discovered frequent restarts (every hour) in the unbound log. Is this normal or is something wrong?
Related to your ISP lease renewal ? Status: System logs: General:

Nope, nothing correlates in system logs. I do have Dynamic DNS setup though but that only updates once per day, so doubt it's related.

One thing is clear in my case : Every time the dhcp service writes leases to leases file the unbound service restarts…every single time.
-
Inq - I just noticed that one of my network devices (Apple TV) was going crazy asking for dhcp every few seconds. I did a clean install of 2.2 and didnt reboot some of my devices, which probably caused this issue.
I am now thinking that this issue could have been causing the frequent unbound resets. I will monitor and update this thread.
Thanks,

It would be interesting and probably helpful to see your DHCP server setting and your unbound settings.
-
Ok, this issue was definitely caused by a misconfiguration on my Apple TV (connected to both wired and wireless simultaneously). This was causing the Apple TV to get stuck in a DHCP request loop (verified by DHCP logs).
In addition, I have the following setting in Unbound: Register DHCP leases in the DNS Resolver
Since I corrected the Apple TV issue, the hourly unbound restarts have stopped.
Thanks,
Marco -
Sounds like something I see lots of people doing with laptops. Plugging in wired while wireless is still on. Same with IP Cams.

@Inq:
One thing is clear in my case : Every time the dhcp service writes leases to leases file the unbound service restarts…every single time.
I noticed the same thing the other day, unbound restarting every time the dhcp service wrote the leases file, about once an hour. It hadn't been doing this until I changed the setting for "unwanted reply threshold" in the dns resolver advanced settings from disabled to 10 million. I changed it back to disabled yesterday and unbound has not restarted since. No idea what the relationship is, but there seems to be one.
edit: nevermind, changed another setting in dns resolver and now unbound is restarting at the same time the dhcp service writes the leases file again…
-
I'm experiencing the same problem with Unbound. Does this mean that it's normal for it to restart if the option to "Register DHCP leases in the DNS Resolver" is enabled?
-
edit: nevermind, changed another setting in dns resolver and now unbound is restarting at the same time the dhcp service writes the leases file again…
I see the same thing: Unbound is restarting on every DHCPREQUEST - DHCPACK sequence:

I guess, when "Sending HUP signal to dns daemon" is fired, Unbound restarts.
At that moment, on the "Status: System logs: Resolver", I see (reversed time order):04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: start of service (unbound 1.5.3). 04-06-2015 09:52:08 Daemon.Notice 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] notice: init module 0: iterator 04-06-2015 09:52:08 Daemon.Notice 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] notice: Restart of unbound 1.5.3. 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: 0.524288 1.000000 1 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: 0.262144 0.524288 2 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: 0.131072 0.262144 1 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: lower(secs) upper(secs) recursions 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: [25%]=0.262144 median[50%]=0.393216 [75%]=0.524288 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: histogram of recursion processing times 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: average recursion processing time 0.414164 sec 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: server stats for thread 1: requestlist max 4 avg 1 exceeded 0 jostled 0 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: server stats for thread 1: 4 queries, 0 answers from cache, 4 recursions, 0 prefetch 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: 0.524288 1.000000 4 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: 0.262144 0.524288 5 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: 0.131072 0.262144 3 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: 0.065536 0.131072 3 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: 0.032768 0.065536 3 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: 0.016384 0.032768 1 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: lower(secs) upper(secs) recursions 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: [25%]=0.08192 median[50%]=0.240299 [75%]=0.484966 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: histogram of recursion processing times 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: average recursion processing time 0.331678 sec 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: server stats for thread 0: requestlist max 28 avg 3.36842 exceeded 0 jostled 0 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: server stats for thread 0: 25 queries, 6 answers from cache, 19 recursions, 0 prefetch 04-06-2015 09:52:08 Daemon.Info 192.168.1.1 Apr 6 09:52:09 unbound: [53865:0] info: service stopped (unbound 1.5.3).
This means that unbound restart several times per minute … is this normal ???
Or is this what it is all about, the setting "DHCP Registration" on the "Services: DNS Resolver" page ? -

And in general, the "wheeeeeeeee something might have changed (99% of cases absolutely nothing at all changed and apinger just went haywire as usual) so lets restart all services and packages" mentality that pfSense has grown is an absolute disaster. (Recently, someone finally nuked this nonsense on routing packages like OpenBGPD/Quagga where it was making them just completely no-op.)

I upgraded to 2.2.1 and this is still occurring very frequently for me.
