Hi Team,

I am using CentOs as an OS For one Audit Management Application(ELM).

Everything was working fine but suddenly OS is prompting the below message.

message from syslogd@
acuarm kernel:Disabling IRQ #177

Where acuarm is the host name of my machine.

When I try to access my application .Its prompting for the below error.

Error:Error getting query result:Run query:Host does not exist.

Please help me out.

Thanks,
Namit

Welcome to the CentOS fora. Please see the recommended reading for new users linked in my signature.

You have not supplied sufficient information to get good help. Check /var/log/messages and dmesg for other references to IRQs and specifically to 177. The error appears to be related to networking. Is networking otherwise working?

It might also help to [url=http://www.centos.org/modules/newbb/viewtopic.php?topic_id=28723&forum=54]provide more information about your system[/url] by running "./getinfo.sh" and showing us the output file.

Hi nmishra3,

I experienced the same error!
The reason for "Host does not exist" error, is because, when this IRQ message occurs, it disables your network as well for some reason!
By running "service network restart", you'll be able to resolve the issue... for now! Why it happens, im still trying to find out!

@pschaff , i will get back to this forum with the ./getinfo.sh data as well! Hopefully it can be resolved!
As we use Centos for our client servers and this problem only started recently, We've been trying to figure out whether its got something to do with hardware (Motherboard) --> as it is the only components that change with the latest servers that we installed! (and which experiences this problem)

Thanks in advance!
