Error Message on Login Screen

[rayle]

Hi all,

I deployed a Redhat 9 (kernel: 2.4.20-8smp) on a Dell 2650 (2 Xeon CPUs) to act as a file server. I also setup a cron job to run every minute of rsync for copying files from one location to another location.

However I sometimes found error message on the login screen like the following quote. What is the possible cause for it? How to solve it?

Thank you very much.

Regards,
Raymond

its something to do with the kernel

I would post it on the kernel mailing list - see here for details: http://www.kernel.org/

btw, when posting on linuxforums.org, you only need to post your question once.

Thanks,

Jason

Thank you James.

I will keep an eye on the mailing list archive at http://www.ussg.iu.edu/hypermail/linux/kernel/

But what would be the subject when you post it? So I can notice your thread easily.

Thanks again.

Regards,
Raymond

When i said "I would post it on xxxxx" i meant "If i was you, try posting it on xxxx", & my name is Jason, not James

sorry for the confusion.
