AlmaLinux is rebooting with no root cause

Support
1

Hello,

I have a 9.2 Alma in my env actually, we have a strange behaviour happening, the AlmaLinux is rebooting almost everyday, with no root cause for it, the UID 0 just stop in logs of messages and secure, and after this the Alma is going to reboot.

The logs:

If you look in these logs, dont have a specific cause, it just stops and starts the proccess of reboot.

secure log shows just the shutdown command happening:

type=SERVICE_START msg=audit(1688661462.885:16): pid=1 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0 msg='unit=dracut-shutdown comm="systemd" exe="/usr/lib/systemd/systemd" hostname=? addr=? terminal=? res=success'UID="root" AUID="unset"

I alredy searched for crons in cron.d/ crontab or root cron and everything in /var/spool/cron/ but no success with that, also i have changed the kernel, and we are updated in the last dnf update.

Any clue or someone have passed for something like that?
Thank you!

I did faced some issues like this with Linux few years back, after checking I found out that my PC cooling FAN was not working
I changed the power supply and the FAN, and I was able to use the system for some more time
Please check for colling fan, heat sink disconnectivity and power supply issues
thanks

Hello, My environment is an KVM VM, sorry for not specify, we have no issues on the node, or temperature protections happening. Thank you for your asnwer.

We need more (earlier) logs than that, that’s just showing the shutdown phase, not what caused it beforehand. Also is it shutting down or rebooting?

I’ve seen sar (system activity accounting tool) cause heavy load and a lot of logs, could be that.

i assume its a mailserver, so does it have enough free disk space - not crashing due to full disk or something?

Yes, its an postfix pure server, without painels or whatever. Just a simple mail server with postfix and dovecot.

all time are running in BRT, i am using vmware esxi license free 6.5, i have other boxes running on this node and everything is fine with these boxes.

Thank you guys!

looks the same as this which i don’t think was ever resolved:

its weird as it looks like it starts up and then immediately shuts down. also i thought you were using kvm, esxi 6.5 doesn’t really support the el9 versions

We have another box using esxi 6.5 under alma 9.2, and no issues was identified. Any clue what can be here? Or something that i can start to view?
