AdGuard Home Crash/Hangs while updating filters

[bostonnm21]

Prerequisites

Please answer the following questions for yourself before submitting an issue. YOU MAY DELETE THE PREREQUISITES SECTION.

• [Yes] I am running the latest version
• [Yes] I checked the documentation and found no answer

Issue Details

• Version of AdGuard Home server:

  • v0.99.3

• Operating system and version:

  • Debian GNU/Linux 7 \n \l

• PRETTY_NAME="Debian GNU/Linux 7 (wheezy)"

• NAME="Debian GNU/Linux"

• VERSION_ID="7"

• VERSION="7 (wheezy)"

Expected Behavior

• While filter update is in progress AdGuard home should continue to be available and serve DNS request.

Actual Behavior

• While filter update is in progress AdGuard home should becomes unresponsive/Hangs and DNS request goes unresolved/Dead internet

Additional Information

• I have about 25 Filter URL and I noticed that some of them take long time to update which might be the reason for AdGuard Home to hang. If I un-check few big ones and then run update, it completes.
• Was thinking if we can with have a timeout or way to update filters in Batches , might help.

Could you please post the list of your filters from AdGuardHome.yaml? This will help us reproduce the issue.

Hmm, nothing too problematic.

To troubleshoot this issue we need to see AdGuard Home logs.

1. Configure AdGuard Home to collect logs:
   • Specify log_file
   • Set verbose to True
2. Restart AdGuard Home and reproduce the issue
3. Post the log file here.

[bostonnm21]

Sure.. here is log file.

AdGuardHome_Debian.log

FYI- Today Application didn't crashed while updating filters. It did crashed just before when I didn't had log file specified.

Thanks again.

[szolin]

Please reopen the issue when the problem appears again.

[bostonnm21]

Please reopen this issue as application crashed today. UI was hung while updating and NO dns request was getting answered. Logs attached.

UI was hung while updating

It's normal - the update process takes time!

NO dns request was getting answered

I don't see it in logs - everything seems normal. What DNS requests were not answered exactly?

[bostonnm21]

I opened google.com and few other random sites and none were working(Timeout error), once I rebooted device all came back to normal.

My internet was fine during this time as devices that doesn't use AdGuard Home were working fine.

[ameshkov]

Most of the errors in the log are not about filter lists, there's an i/o timeout error as if something was wrong with the network access in general

@szolin there's another issue in the log: 2019/12/10 14:18:18 22970#202453 [info] Couldn't write config file: Couldn't start forwarding DNS server, cause: could not reconfigure the server, cause: couldn't listen to UDP socket, cause: listen udp x.x.x.x:53: bind: cannot assign requested address

But I assume it will be fixed in v0.100.
