Hi Akshay,
I tested this issue on AXP 1.6.1 by changing the hostname in the guest application configuration portion and then reloaded the service module after saving the change. The correct changed hostname still appears after typing ¿uname ¿n¿ in the Cent OS guest environment. It appears that you may be using the User Defined Linux environment and have installed your own guest OS. I suggest that you run an strace on ¿uname ¿n¿ to determine which libraries may be the cause of your issue. I¿ve included this information from my own strace below.

Subject: New Message from Akshay Punja in Application eXtension Platform (AXP) - Technical Questions: AXP application hostname configured does not retain
Akshay Punja has created a new message in the forum "Technical Questions":
--------------------------------------------------------------
Hi All,
I have installed Linux HA in AXP 1.6 enviornment and is working fine after some amount of customization. But after installation of Linux HA rpms I see a strange issue.
Linux HA has some processes that run only if proper local hostname is configured.
so inorder to configure the hostname I add the following configuration in gobal AXP config using the cli
$> configure terminal
$>hostanme xyz
$>appservice <application name>
$>hostname <xyc.com>
$>ip domain-name <domain.com>
$>exit
$>wr mem
if I login to the shell prompt and type uname -n i see the configured hostname but if i restart or reset the blade or vm, the hostname changes back to localhost.localdomain . I checked /etc/hosts file it contains the <ip address><hostname.domain.name. but uname -n always results to localhost.localdomain after restart
Following are the list of rpms installed. I think the issue might be from an rpm installed
