Unbound crashed
« on: April 08, 2018, 10:02:58 pm »
I wasn't doing anything spectacular, i was working via a rdp connection when everything went dark, suddenly no more internet (apparently). When logging into the WebGUI, i noticed Unbound wasn't running anymore.

I found these in the logs:

Code: [Select]
Apr  8 21:35:04 gateway configd.py: [23ab9b35-a78b-4362-9cc8-d36317cc3d9d] Reloading filter

Apr  8 21:39:29 gateway configd.py: [eb29b026-4b4a-436b-b35a-81b9f13bd71e] updating dyndns WAN2_DHCP

What just happened? Did anybody notice anything similar?
First time i ever noticed this. Restarting Unbound got things working again.

Hi there,

Maybe OOM kill? Check the Unbound log too if this happens again.


Cheers,
Franco

Unlikely, unless something is leaking, crashed and freed up the mem, but you never know.. i did check the Unbound logs, found nothing, but i was in a hurry, so maybe i missed something.

I'll get back to this if it happens again with more details.

Thanks!

So... crashed again... also while RDP-ing :)

This time, I found this in the logs:

Code: [Select]
Apr 17 19:11:18 gateway unbound: [90027:1] error: could not SSL_new crypto error:14FFF0E4:SSL routines:(UNKNOWN)SSL_internal:ssl ctx has no default ssl version

Apr 17 19:11:18 gateway unbound: [90027:1] info: error sending query to auth server 9.9.9.9 port 853

And the same error as before in system:

So am I the only one with this problem?
I disabled IDPS, curious if it will crash again...

I have the same issue but related to the DNS-TLS guide (with LibreSSL).

I just checked the errors I had when testing DNS-TLS against 9.9.9.9, they are exactly the same.

Hmm.. ok, so it's not an isolated incident.
Well, I don't know what's next. Maybe opening a bug on Github. I'll do this later today.

Thanks!
