Hi All,

I went to access my OpenVZ hardware node and notice the following errors spitting out on the console - Any thoughts as why these errors are being generated...

Hi,

What kernel runs on this node (uname -a output)?
Please, attach the full dmesg output also.

Thank you,
Vasily

Joe,

As far as I can see from the dmesg output, you have rebooted the node after the problem occured, right? If so, please attach /var/log/messages file, probably it contains needed information.

Do you encounter this kind of messages often? Or it was the only time you've seen it?

Also, you use pretty old OpenVZ kernel. It worths to upgrade.

Thank you,
Vasily

That's all I have... I don't think I save the /var/log/messages... The above is the syslog messages that I got.
Hope that can help!
