Unbound crashes periodically with signal 11
-
I see that also on two 2.5.0 CE machines.
Disable "Register DHCP leases in the DNS Resolver" now and will have an eye on it. -
@salander27-0 :I tried this. Will report back. However, I never had "Register DHCP leases in the DNS Resolver" set.
-
Since the new version of Unbound fixes it, it's unlikely to actually be related to just that one setting (DHCP lease registration), but that is the fastest way to trigger it for some people.
I imagine others are/were hitting it as well in different ways. So there isn't a need to keep tracking potential causes now that we know the upgrade fixes it.
-
@jimp So is the plan then to push 1.13.1 to the stable repo or to try to bisect through the 1.13.1 release in order to find out which patch specifically fixes the issue and just apply that patch to the version in stable?

We'll bring in 1.13.1, there isn't a compelling case to do all the legwork to pick in partial changes at this point. 1.13.1 is a minor patch/bug fix release and the impact is low other than the fix for this which is highly beneficial.
-
@jimp Speak of the devil, looks like it's already been added to the stable repos.
For anyone coming into this thread now, you can run the following command to pull unbound 1.13.1 from the stable/2.5.x repo (I am unsure of how to update system packages from the UI, hopefully someone can chime in there):
pkg upgrade -f unbound(you should see that it is installing
unbound-1.13.1)
Make sure to restart unbound after this package installation.It is probably a good idea for those who have installed the devel package to do this as well just to ensure that your systems are not a mix of devel and stable packages.
-
There isn't a good way to do that from the GUI, but you could run
pkg upgrade -fy unboundfrom Diagnostics > Command Prompt. Be sure to restart the Unbound service from Status > Services after.From the CLI the easiest way to do both is
pkg upgrade -fy unbound; pfSsh.php playback svc restart unbound -
@jimp : I can confirm that the new version fixes it for us.

@salander27-0 fixed it for me too... thank you
-
thank you Jim.
This open and direct communication is really awesome! -
Fixed for me too, 24hrs with no unbound restarts...

Hi
After installing unbound-1.13.1 my unbound is still restarting from time to time.
My system have been unstable for a long time, but I haven't had the time to dig into it. Last week I figured out that it was the unbound which is restarting. So I updated to version 2.5. But still having issues.
I have "DHCP Registration", "Static DHCP" and "OpenVPN Clients" enabled in my DNS Resolver settings.
I will try to test further and report back
Kind regards

@jimp This (upgrade of unbound to 1.13.1) sad fully does NOT fix the issue on my system. Disabling DHCP leases fixed the restarts... but this package upgrade to 1.13.1 (and restart and re-enabling DHCP leases) brought the old behaviour back (restart of unbound about every 10 minutes in my case).
So actually 1.13.1 at least seems to not fully fix the problem for all systems.
UPDATE: but again also disabling DHCP leases again for/with 1.13.1 unbound fixes it again -
The symptom fixed by 1.13.1 is the crash/segfault.
"Restarting" is not a symptom of a problem, it's a side effect of using DHCP lease integration and is normal.
-
Upgraded unbound from the sable repo as described earlier, and still getting DNS Server crashes, not automatically restarting
Next time it happens I'll try and grab a log to post

I think the common factor here is that both @johnpoz and @LostInIgnorance are using ARM devices here which presumably uses a different stable repository with ARM-specific packages.
Unfortunately I know little about this but perhaps @jimp can chime in with if/when an updated package can be expected to be available for that architecture.
