really strange. I have here one intel NUC with UCS 4.4.2 installed. The NUC runs as backupdc. It is working fine, but only 6 hours. After this time the computer is not reachabel anymore. If i pluged in an monitor and an keyboard, i can’t see anything on the screen. ACPI didn’T work. So System is in freeze state.
But after i pluged in Keyboard and Monitor, the System is running fine without problems, last test over 8 days. I don’t understand this. I’ve changed a lot of things in the bios, but no changes at the behavior.
Maybe it depends that a graphical screen is starting without monitor?
I’ve configured remotelogging with rsyslog. But at the time if the nuc is going to hell, there is no log, nothing.
Maybe someone have a idea
