LinuxQuestions.org - can't get a daemon to start

can't get a daemon to start - says it's already started

I have a program called Simple Signalling Daemon from APC that is supposed to shut down the server when the unit switches to battery power. It used to run fine:

Code:

# /etc/rc.d/init.d/apcssd start 

Starting APC Simple Signalling Daemon: [OK]

It's supposed to start when the server boots up.
For the last while it hasn't been starting, when I try to run it manually I get:

Code:

# /etc/rc.d/init.d/apcssd start

Starting APC Simple Signalling Daemon: Only one copy of ssd may be running at a time [FAILED]

but when I do:

Code:

# /etc/rc.d/init.d/apcssd status

ssd dead but subsys locked

# cat ssd.pid

(empty)

# rm /var/lock/subsys/ssd

rm: remove '/var/lock/subsys/ssd'?: y

# /etc/rc.d/init.d/apcssd status

ssd is stopped

# /etc/rc.d/init.d/apcssd start

Starting APC Simple Signalling Daemon: Only one copy of ssd may be running at a time [FAILED]

and ps aux | grep ssd is empty as well.
So I am pretty sure my ssd daemon is NOT running. but I can't figure out why it won't start. My server gets rebooted about twice/week (due to locking up) so it's not that it needs rebooting. I have Mandrake Multi Network Firewall operating system (kernel 2.4.18-8) and this is a production server. Any ideas?

try reinstalling the daemon....

Reinstalled from source (tar.gz) downloaded from APC, same version (2.0.1). Same error. Any other suggestions?

have you checked the file /etc/rc.d/init.d/apcssd for the reason that causes the echo "Starting APC Simple Signalling Daemon: Only one copy of ssd may be running at a time [FAILED]"?

Here is the contents of the apcssd file:

Code:

. /etc/rc.d/init.d/functions



case "$1" in

  start)

        # Start daemons.

        echo -n "Starting APC Simple Signalling Daemon: "

        daemon ssd /etc/ssd.conf

        echo

        touch /var/lock/subsys/ssd

        ;;

  stop)

        # Stop daemons.

        echo -n "Shutting down APC Simple Signalling Daemon: "

        killproc ssd

        echo

        rm -f /var/lock/subsys/ssd

        ;;

  status)

        status ssd

        ;;

  restart|reload)

        $0 stop

        $0 start

        ;;

  *)

        echo "Usage: $0 {start|stop|restart|reload|status}"

        exit 1

esac



exit 0

I tried to manually type the commands given under "start" but I got the error: bash: daemon: command not found

ssd.conf reads:

Code:

TTY = /dev/ttyS0

MaxBatRT = 300 # five minutes

hi!

this is NOT the area where i have much know how .... but i think, "daemon" is a function defined in /etc/rc.d/init.d/functions. yeah. checked in on mdk 10.1.

the daemon-function checks if the pid-file is there. not its content. please delete the pidfile and retry starting.

Yeppers, I'm still having this problem. Same error, same everything.

"Service apcssd start
Starting APC Simple Signalling Daemon: Only one copy of ssd may be running at a time [FAILED]"

even though I deleted /var/lock/subsys/ssd

There is no pid file associated with ssd.

It gets hung trying to start /sbin/ssd which is a binary file I can't read with vi. I don't know where it is checking before it gets the error "Only one copy ..."

Please help!!!

WOOHOO!!!! I found it!!!

There was a "hidden" pid file in :
/usr/local/share/ssd/ssd.pid

once I deleted it, my daemon can now start with [OK]

I found it on a russian website that happened to list all the files associated with ssd and their paths.

Thanks for the input
