WebGUI unaccessible for 3-4 minutes --> when modyfing "Interfaces"

[AES777GCM]

Regarding bug-hunting: Isn't it helpful when developers know now that "killing" the lighttpd task manually (while system is in status "locked") brings the Web Gui instantly back to live ?

Pls have a look @ my posting from 18th Nov 03:28pm.

Is this problem taken seriously?
I hope so.

However - thank's in advance @Franco and Team!!!

Can you tell me the minimal configuration and environment which can reproduce this?

Minimal configuration would be any configuration changes after a clean install.
Environment would be if it can also be reproduced without any external infrastructure involved. Direct connection of client to Opnsense hardware

If there are switches, ISP routers or whatever involved it makes it harder to reproduce since it can be many specific factors in your personal environment I do not know.

Does it have to be random hardware? I still have an old intel core2duo pc around if thats needed for reproduction. I ran opnsense on it before like 4 years ago I think.

Hello Cedrik,

at first thanks for your reply and intention to look this up.

My setup is really simple basic: WAN put in em1; LAN in em0. LAN connected to a layer 2 switch - pc directly connected to this switch.

Installation of fresh 24.7 --> then update via console to 24.7.8.
After reboot login as root (WEB GUI)--> run initial setup.

Then act as you want to do anything on WAN interface - like OPT IN "Prevent Interface Removal" --> Save --> APPLY

This "Apply" leads on my 2 Systems (HUNSN / FUJITSU) to the above mentioned system stall.
Its very interesting how your system react and if it the same, what might be the problem.

Cheers,
Udo

[Monviech (Cedrik)]

Does your system react the same if WAN is disconnected, the Layer 2 switch does not exist, and your client is plugged into LAN directly?

Please deconstruct your setup a bit more for a common baseline.

[AES777GCM]

I hardly can use a Firewall with WAN disconnected and an unbroken, unmanaged Layer 2 Switch can't be a factor.

As I said - when the lighttpd task is killed manually the WebGui pop ups directly again of the former struggled system.

But I can find out on thursday what you proposed.
Do you have a "special idea" by asking this for?
How does your System behaves?

[Monviech (Cedrik)]

My systems (mostly DEC740 and 750) as well as my developement and general use VMs all work without issues. Thats why right now I want to rule out outside factors in your environment. Asking you to disconnect all outside factors is not to make your system unusable, but to see if the issue still happens.

Thats common troubleshooting practice, deconstructing a setup until the issue is not present, and then slowly introducing more complexity until it happens again.

Digging around on the box itself would be far more productive but thats commercial support scope.

EDIT:

Looking at the lighttpd error logs you provided makes it look like the graceful shutdown of the process fails. It seems to wait for something, e.g., all connections to close. Thats why killing it fixes it for you, the graceful process shutdown fails.

[AES777GCM]

Okay - got the point.
I'll give report on thursday. Thx in advance for your support.

cheers,
udo

Hello Cedrik,

I tried already and - bad news - When disconnect WAN - nothing happens regarding this issse.
Second - directly plugin of LAN had no impact, too.

It keeps on being "weird".

Btw: Patched up to today's latest version (24.7.9_1) and (as expected) nothing changes - issue is same.

[Monviech (Cedrik)]

Hey thanks for trying and confirming that it must be an isolated hardware/software related issue. I'll install the latest version on some old and new hardware and see if I can reproduce the steps you outlined.

[Monviech (Cedrik)]

I just tested a fresh installation on a DEC740, couldn't reproduce the issue.

Also had IPv6 on WAN with DHCPv6 just to ensure parity.

Next I dusted off some pretty ancient hardware.

Tarox Digital Machine
Intel Core Duo T6600 2.2ghz
2GB DDR2 RAM
64GB SSD
Realtek Nic

I could only install 24.7 on it, updates would fail since its too bad. But clicking aroun, saving and applying the interface settings in 24.7 did not make the web GUI freeze like in your case.

EDIT:
It didnt update cause my time was wrong lol
