I loose connection in server and have guys in DC to rebooted server. Then when I check logs only thing I see at connection lost time:

Oct 31 12:00:20 s8 CRON[911689]: pam_unix(cron:session): session closed for user root
-- Reboot --
Oct 31 12:22:11 s8 kernel: Linux version 5.15.64-1-pve (build@proxmox) (gcc (Debian 10.2.1-6) 10.2.1 20210110, GNU ld (GNU Binutils for Debian) 2.35.2) #1 SMP PVE 5.15.64-1 (Thu, 13 Oct 2022 10:30:34 +0200) ()

So what does this -- Reboot -- mean? Is it manully rebooted? Or pve rebooted itself? And if yes what log should I check ?
 
My Friend I have a similar problem with my machine too, the only thing is that my logs are empty of errors...!!! Nothing there..!!!
I think that this happened after an update..!! Did your machine freeze??? Or just rebooted with all VMs and LXCs closed???
 
I do not think it has frozen. Just rebooted wht only -- Reboot -- in logs. I asked guys in DC if someone has rebotted it but it is not possible. So what does that "-- Reboot --" text in log mean I wonder. Hardware is new.
 
no, that just means that the message before and after that line have a different boot_id attached. the boot_id is set by the kernel when booting
 
It happened to me but I assumed it was after some critical update..!! But then I realized that I haven't done any update so what was wrong????
See my previous post about freezing and you will understand.
 
lots of possible causes: freezing and manual hard reset, power loss, crash without a chance to log anything to disk, ..
 
In case there is a BMC you could log in there and see if it logged something. My IPMI is logging failing fans, too high temperatures, power losses and so on.
