Locked up

[KenGordon]

On a random basis, after my system has been on for several days, my entire FreeBSD 14.4-RELEASE system will suddenly simply lock up. Everything comes to a complete halt. The only way I have found up to this point to get out of it is to turn the computer off, but this results in having to go into single-user mode, etc. at the next boot.

I am using the Illumina desktop.

Is this a "normal" occurrence? Has anyone else experienced this?

Is there some way to recover from this lock-up withOUT simply killing the power to the box?

Will simply waiting allow the system to recover on its own? If so, how long must one wait?

As you can imagine, this is extremely annoying.

Does the same thing happen if you boot another OS? If yes, i think it's a heat problem. Dust maybe.
Or maybe check RAM for loose connections.

Does it still react to network pings?

The single user thing after unclean shutdown is a fsck configuration thing. You should show your rc.conf. And tell us what graphics hardware you have.

Does a remote terminal that monitors the system log show something at the final moment? If it's the graphics card of USB causing freezing, you could still see something happening on a ssh connection.
Also, if ping says "host not found" instead of timeout or no reply at all, the network card is still up, which means no full hardware freeze of a memory, CPU or temperature problem.
