NUT diagnostics page is empty

**Important notices** Before you add a new report, we ask you kindly to acknowledge the following: - [X] I have read the contributing guidelines at https://github.com/opnsense/core/blob/master/CONTRIBUTING.md - [X] I am convinced that my issue is new after having checked both open and closed issues at https://github.com/opnsense/core/issues?q=is%3Aissue **Describe the bug** If i go to "Services -> NUT -> Diagnostics" ("Dienste -> NUT -> Diagnose") the page is empty. ``` [016ff341-9559-4a2b-bd4f-322c15104466] Script action failed with Command '/usr/local/bin/upsc 'ZeroUSV@192.168.116.250'' died with <Signals.SIGSEGV: 11>. at Traceback (most recent call last): File "/usr/local/opnsense/service/modules/actions/script_output.py", line 93, in execute subprocess.run(script_command, env=self.config_environment, shell=True, ~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ check=not self.disable_errors, stdout=output_stream, stderr=error_stream) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.13/subprocess.py", line 577, in run raise CalledProcessError(retcode, process.args, output=stdout, stderr=stderr) subprocess.CalledProcessError: Command '/usr/local/bin/upsc 'ZeroUSV@192.168.116.250'' died with <Signals.SIGSEGV: 11>. ``` Any command via commandline upsc is throwing segmentation faults: ``` boronsbruder@zerofw:~ % upsc -L 192.168.116.250:3493 ZeroUSV: USV Server Segmentation fault ``` On the host everything is running fine. UPSC is working without SEGFAULTS. ``` boronsbruder@zeroserver:~$ upsc -L ZeroUSV: USV Server ``` Nothing changed in the setup for NUT. NUT is running as a netclient. **To Reproduce** Steps to reproduce the behavior: 1. Go to '"Services -> NUT -> Diagnostics"' or 1. open commandline shell 2. use any command on upsc e.g. 'upsc -L {host}' 3. See error **Segmentation Fault** Expectation: Data from the Host_USV are showing up. UPSC not ending with **SEGMENTATION FAULT** **Screenshots** <img width="603" height="427" alt="Image" src="https://github.com/user-attachments/assets/c8c8a167-18b9-417c-bb71-1a75ae19756c" /> **Relevant log files** here is a part of the system.log ``` 2026-05-13T15:44:01 Notice kernel <6>[31249] pid 26225 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:59 Notice kernel <6>[31247] pid 8743 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:57 Notice kernel <6>[31245] pid 8531 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:55 Notice kernel <6>[31243] pid 8282 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:53 Notice kernel <6>[31241] pid 443 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:51 Notice kernel <6>[31239] pid 93116 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:49 Notice kernel <6>[31237] pid 75679 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:47 Notice kernel <6>[31235] pid 74836 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:45 Notice kernel <6>[31232] pid 74355 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:42 Notice kernel <6>[31230] pid 66602 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:40 Notice kernel <6>[31228] pid 57565 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:38 Notice kernel <6>[31226] pid 48664 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:36 Notice kernel <6>[31224] pid 48295 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:34 Notice kernel <6>[31222] pid 44561 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:32 Notice kernel <6>[31220] pid 34790 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:30 Notice kernel <6>[31218] pid 26290 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:28 Notice kernel <6>[31216] pid 15687 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:26 Notice kernel <6>[31214] pid 15368 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) 2026-05-13T15:43:24 Notice kernel <6>[31212] pid 9172 (upsc), jid 0, uid 0: exited on signal 11 (no core dump - bad address) ``` **Environment** Software version used and hardware type if relevant, e.g.: ``` Typ opnsense Version 26.1.8 Architektur amd64 Commit 76ed1ef85 nut 2.8.5_1 os-nut 1.9_1 Hardware: Lancom UF-160 ```
