I think the Linux iele 2.6.22-15-server [#1 SMP Fri Jul 11 19:54:13 UTC 2008 i686 GNU/Linux] of a friend of mine has problems. Her Joomla! site went down for a while and when I check dmesg I get:

What does this mean and why do you think the server does this? My server knowledge is limited so I am learning as stumble along..

Hi,

Looks like a dodgy network cable/screwed up switch or network card.

Linux is just telling you that the network card is loosing it's connection to the network, then getting it back and when it tries to set the link to 100Mbit the connection dies again.

If it's worked up till now then I guess someone has damaged the network cable.

Regards
Ian Dobson

Thanks for that answer Ian! Will ask her to check.
