Hello everyone,

Yesterday one of my proxmox servers starting to randomly restart itself every few hours. It had previously been running for a couple of weeks without any problems. I've checked the logs but don't see an obvious reason for the reboots. Maybe I'm missing something? Thank you in advance for any advice.

Info & Hardware:
  • Proxmox 4.4-1/eb2d6f1e
  • Dual Intel E5-2630 v4
  • Supermicro X10DRL-i
  • 128GB Ram
  • 4 x 2TB Samsung 850 Pro + LSI 9271-8i
  • Local LVM storage is used for VMs
  • Supermicro IPMI event log shows no errors
  • Supermico IPMI reports PSU status as ok, power logs never show a drop in power
Here is a snippet of code from the syslog from the latest reboot today, Apr 25 17:17:07.

Thanks again for any help you can offer.

This kernel has a bug, just update to latest and your issues are gone.

Unfortunately this didn't solve the problem, and the server rebooted itself today.

Hi!
This syslog contains the system boot only. Apparently after reboot.
Need 1...2 of minutes of syslog before reboot.

Best regards,
Gosha
 
Hi,

Thanks for your reply. The reboot happened at Apr 28 10:18:52 so the syslog started at about an hour before it restarted.

Here is a longer snippet:

Hi!



Check for disable Watchdog in BIOS.

Best regards,
Gosha

I appreciate the suggestion but it was disabled already before hand and it still restarted.

Code: 
root@node1:~# ipmitool mc watchdog get
Watchdog Timer Use:     Reserved (0x00)
Watchdog Timer Is:      Stopped
Watchdog Timer Actions: No action (0x00)
Pre-timeout interval:   0 seconds

Initial Countdown:      0 sec
Present Countdown:      0 sec
 
Apprciate this is an oldpost but it does come up as a top responder when googleing this fault, i also have a proxmox server which rebooted intermitently,

My setup is as follows

i5
8gb ram
2TB Samsung SSD
GTX970 (Only interface active)
Intigrated GPU (Had to Enable due to reboots)
PSU 700W

I found it would reboot on and off give or take every hour to 3 hours however it was garented to reboot when you luanched games it seemed to last longer actualy you would get through playing for example GTA5 for hours no reboot as soon as you closed that off did a bit of webbrowsing it dropped and i mean the whole server rebooted,

i changed settings from top to bottom in the hardware section harddrive settings CPU everything nothing resulted in the reboots stopping i was thinking PSU so i checked all connections re-seated the GPU made sure cables were nice and snug, But no still reboots occururd,

I searched though the logs to see if i could find out anything before the reboots but nothing

Recently i weas thinking back to when i Orginaly setup Proxmox with no External GPU and it dawned on me i had it running for 3 days solid with no reboots thats when i decided to re-enable the intigrated GPU as part of the VNC setup and from then on i have not seen 1 reboot playing games browsing and more,

the only reason i know this is the culprit is i re-disabled the intigrated video and quick enouth the reboots came back,

hopfully this helps someone els thats looking for an answer to there unixplained reboots?

Thanks
