CentOS - Mar 2011 - kernel NETDEV WATCHDOG: eth0: transmit timed out

Hi , all :


Sometimes  my server network connection on Linux goes down with short
message in syslog saying: "[localhost kernel] NETDEV WATCHDOG: eth0:
transmit timed out" (or similar).

By the way , I installed the CentOS 5.4 x86_64 bit and the kernel version
was  2.6.18-164.

Has anyone experienced this problem or is it the bug of the kernel ?


I restart the network and that problem have resolved just now.

It usually happens with problems on the physical layer. You network card
may be bad, or the connection, or the other side of the ethernet wire, or
a driver problem in the linux kernel. We don't have enough information
from you so say more.

How are you connecting to the 'Net? Is this a commercial line, or only,
say, DSL?

       mark, just fought the good fight with Verizon over the latter

5.4 w/o updates is 1) (more) buggy and insecure 2) behind on driver versions. 
That's one general and on specific reason for you to type "yum
update"
(preferably before you invest too much time investigating this hw/driver 
problem).
