Hello, Thank you very much, Tobias, Tomasz and Kenneth, for your answers. I should have told you the "computer" is a fanless unit, powered by an AC adapter. Its output is 12V 5A.That could explain the voltages anomalies.The AC adapter was buried under a pile of cables. Following your messages, I dug it out and put it near the computer.That way it will be cooled by the 12cm fan I installed on the computer since I get those freezes.That AC adapter was sold with the unit when I bought it. It's a low end made in China AC adapter, I could also look for a better quality adapter. The computer has an HDMI output. I'll plug in a monitor if it freezes again. Thank you again, your help is really appreciated ! Nicolas, Paris. Gesendet: Montag, 18.

Hello, I encounter a freeze on my OpenBSD 7.1 router. I have to reboot it. When that happens, there's nothing special in the /var/log/messages file : Jul 17 06:00:01 system syslogd[8620]: restart Jul 17 21:00:25 system syslogd[97469]: start Jul 17 21:00:25 system /bsd: OpenBSD 7.1 (GENERIC) #443: Mon Apr 11 17:55:15 MDT 2022 That happened several times. At first I thought that was a temperature related issue. So I installed a large USB fan on the case, and the case is at the room temperature of 25�C. I don't know how to diagnose that issue. Do you have a monitor attached to your router? If not, attach a monitor so you can see any error messages that may be displayed on the console. In particular, if the freeze is due to a panic, you will need to be able to see the console display to diagnose it. -ken
