sudden server down

[tincboy]

Hello,

I've a Proxmox server with about 10 VMs,
It goes down every day, but the htop, atop, iftop, syslog show nothing unsuall, no error, no high load, no IO activity.
I've changed all hardware twice except HDD drives ( which seems to be safe )
But the server still goes down every day.
Any one has any suggestion on how to find out the cause of issue.

But the server still goes down every day.

You're losing network connectivity or server just reboots?

Server reboot is required, no connectivity issue has been seen

If i understand this correct: server does not respond to ping replies and you need to reboot it to get network back online again?

 

[tincboy]

Yes you've understand it right.

What network card do you have in your server? the r8169 driver is known to suddenly stop working so if you have one of the network card requirering this specific driver and if the card is also supported by Realtek's own driver r8168 you should use Realtek's driver.
