I'm having some issues on a server running redhat for specific application and lately it has been for some reason kicking out some services... I just checked the Logwatch mail on the root user and here is one of the main error:

Kernel Errors Present
I/O error: dev 08:00. sect...: 6time(s)
sda: I/O error: dev 08:00, sect...: 6time(s)

I've read on a couple of sites about hard disk issues and would like to know a little more and confirm that this is what it is.
Thanks

Has the server been rebooted recently? Check uptime.

To get more details about that (truncated) message, of course check /var/log/messages.

Anomie,

Yes actually i restarted that server like 3 weeks ago now. It seems that it keeps on dumping one specific running service. so has i didn't know if this server had been restarted recently i decided to do it and to my surprise instead of rebooting normaly it actually displayed an error message:

i took a picture of this messages then as it was frozen i had to hard reset it (on/off)
Then it actually booted normaly.
