Update Problems version 26.7.6 Unbound fault

[CK_beats]

Hello community,
I could really use your help with the update to version 26.7.6.

The update process completes normally, the firewall restarts (Microsoft Hyper-V) and boots without errors.
However, Unbound DNS fails to run afterwards.
If I start the service manually, it runs for about 5 seconds before the following error appears in the log:

Code Select Expand

[8815:3] error: pythonmod: Exception occurred in function operate, event: module_event_moddone

From the specific Unbound logs, I was able to see last night that the buffer was unavailable. However, during a second attempt, I increased it to 10 MB (up from the default 4 MB).

Since Unbound won't start, nothing else is working, of course.

What did I do wrong?
Our OPNsense instance runs as the core router directly connected to the FTTH modem (VLAN 7). Apart from that, it manages 3 VLANs and handles DNS and DHCP; Squid and HAProxy are, of course, essential components.

Everything is standard, except for one third-party plugin (os_abusedipdb).

Has anyone else perhaps run into this same problem?
Up until now, all updates have always gone through without issues.

Best regards,
Constantin

Hi Constantin,

Can you test this kernel?
