Current uptime is 151 days :]
No reboots since then.

Thank you very much, Support Team! <3
I want to believe reasons for those mysterious hard reboots were solved.

@xvd
Many thanks for advices!
I probably use them if it would happen ever again.

Productive week for everybody!

[xvd]

Share with me, how long was the maintenance, and what it was like? Sudden shutdown and engineer intervention, or email reply with exact date? I run some production stuff here and want to be prepared if it would be possible.

Few observations:

1. Using the online ticket system (in the control panel) lead nowhere - it would typically take 2-3 days to get an answer and mostly they do not bother reading the ticket. It is more like a robot replying with the next answer from the list. Altogether they asked me 3 times for the results of the hardware tests (run in rescue mode) and 4 times for the permission to do the intervention.

2. In the end the only way how to convince SYS to do anything was to call them and to insist that there is something wrong with the server even though their tests show otherwise (at that point I was 99% convinced that it was a hw problem).

3. I called them on Friday morning and I was promised that a motherboard will be replaced before the end of the business day. Few hours later I saw another ticket "Power Supply Replacement" in the control panel. So you will probably not get the exact hour when the intervention will take place. Moreover, you will have to confirm that all data is backed up. The fact that in the end they replaced the power supply rather than the motherboard makes me think that once somebody who knows what they are doing gets their hand on the server they are quick to determine what is really wrong and fix it ... but to get to that point was an ordeal.

4. I don't know how long the intervention took place but I think it was reasonably quick.

Good luck with your server!

Kamilleri - FYI in my case it seems that replacing the power supply resolved the issue. Fingers crossed.

Wow! Glad to hear that!
Wish your SYS server would never go offline again. Thanks for reply, and thanks SYS support for attention to your ticket.

How often do you experience them?

It is quite random. I was not able to find any pattern. Sometimes it is OK for few days and sometimes I get into an infinite loop of reboots. When I ping the server I get around 10 replies before there is another reboot. It lasts until somebody from SYS gets the email from the real time monitoring system. Then they do "something" which stops the loop. They never tell me what - they just send email with "Server on login, Ping ok, Services started".

I am quite convinced that it is hardware related. Especially when I run nearly identical servers which are fine.

Have you tried to contact the support? I did. Quite unsuccessfully though - according to them there is nothing wrong with the server and after that they ignore me.

How is your server Kamilleri? Did turning off RTM work for you?

I don't know yet, waiting for next hard reboot.
But I'm almost sure that RTM wasn't the case, and I begin to think this is somethind hardware related (power supply or something related to broken motherboard/cpu/ram or compability issues). Run out of ideas.
No signs of software stop or ACPI command.

[Kamilleri]

Just a heads-up , before you disable the RTM process on your server you should switch off monitoring for your sever in the SYS control panel, otherwise the OVH software will think the lack of RTM data means the server has stopped responding and do an auto-reboot for you...

Woah! So thaats what "Monitoring" do. I thought it was related to RTM data (cpu/ram/swap graphs), so disabled it too. Actually this is making sense now, we were already rebooted previously (long time ago) because enabled firewall for ICMP. Ability to opt-out from it is nice, but can length hardware unavailability repairment process.
Anyway, thanks for your time.

[Kamilleri]

The only events happening before reboot in syslog is... RTM cron (real-time monitoring of OVH).
Don't know, trying to disable it.

[Kamilleri]

Ok, this is bongus.
Another reboot happened this morning, without any sign of software issue in syslog.
It's just happened. And that's all.

Very strange and annoying behavior.

Running another memtester session. Previous was OK, and this is making me worry:
If it's not an user/OS request, not a HDD failure (SMART is OK), not OOM, not a temperature issue, then... what could it be?
Power supply issue? Some kind of hardware non-easy-to-reproduce ghostly self-rebooting issue? That's a bummer.
I'm not ready to pay installation fee for another server to migrate.

[Kamilleri]

Doing memtester... hmm, looks like RAM is fine...

Searching around, there's some live memory tester:

https://blog.wpkg.org/2010/11/23/tes...run-memtest86/

Note that you may change the arguments according to your server's free memory.

Woah! That's something new.
I would definitely try this. Thanks for your time!

[Kamilleri]

Do you have the possibility to run memtest86?

That would be a nice start. Sadly it's kinda production server, so I need to find some maintenance window for that.
Thanks for reply. Would hope it wouldn't reboot itself again, as I'm almost sure it's not a software issue.

Before reboot, syslog.
When this happened, there was some iowait (hdd lagged)

Did someone experienced unexpected cold reboots of Proxmox/Linux SYS dedication, happening almost in the same day every month?

root@hv2:~# last -x
runlevel (to lvl 2)   2.6.32-34-pve    Tue Mar 24 08:14 - 09:16  (01:01)
reboot   system boot  2.6.32-34-pve    Tue Mar 24 08:14 - 09:16  (01:01)
runlevel (to lvl 2)   2.6.32-34-pve    Mon Mar 23 08:47 - 08:14  (23:26)
reboot   system boot  2.6.32-34-pve    Mon Mar 23 08:47 - 09:16 (1+00:28)

Both of those wasn't issued by me or my systems,
and the bootlog is starting without any trace of reboot command.

Trying to find a reason for that.
