daemon dies !!!!!!!!

sachinh · 12-03-2007, 06:43 AM

Hi,

Lets say we have got a daemon called test on one of our application server. We initiate the same at the system startup using script. But daemon is not starting through this script. It shows as Daemon started alongwith the pid in Log files but seems it dies as soon as it starts. Is there any way we can trace the cause of the error??
One more thing, when we manually start this daemon using the script, it starts perfectly.
Can anyone suggest/give any kind of hint as we seem to have confused by now.

Thanx in advance.

So you start some program using some script on some system, and want to know why it fails? I think you're going to have to provide some more information before you can realistically expect any helpful answers.

Ok....I wanted to ask this on a general terms. But if this doesnt help then here it goes.....
The system is Dell 6350 make, with RedHat Linux 2.1 installed on it. The application which we are running on it is UNIFTP. Out startup script ideally should initiate 2 daemons of uniftpd
i> dc & ii> no_dc . But when system boots, it only does start the process for dc and for no_dc (log says) it starts and dies immediately.

Let me know if things are bit clear by now if not plzzz ask me any questions.

Thanx

What does your start-up script look like? (please paste it in [code] tags to aide readability)

Code:

# start two daemons for dc and no_dc

print "\nStarting parent process for DC"
date >> $home_dir/uniftpdSTORES.log
$home_dir/uniftpd DC >> $home_dir/uniftpdDC.log 2>&1
date >> $home_dir/uniftpdNODC.log
print "\nStarting parent process for NODC"
$home_dir/uniftpd NODC >> $home_dir/uniftpdNODC.log 2>&1

# terminate a process
#------------------------------------------------------------------
function terminate
{
        pid=$(ps -eo  pid,command -u $account | grep $1 |grep -v grep |  awk '{print $1}')
        if [[ $pid = "" ]] ; then
                return
        fi
        print "\nShutting down old version of $1"
        print "kill -9 $pid"
        kill -9 $pid
}
#------------------------------------------------------------------

And what does the log file contain?
