No, it doesn't daemoniz or fork anything and
prints stuff to stdout and stderr only -
because I was running it with /etc/inittab
on the CentOS 5.7 (and thus shouldn't daemonize).

The pid doesn't match or I can't get it:

(I've omitted "sudo " below, I use CLI as "afarber"):

# initctl status pref
pref start/running, process 1507
# initctl restart pref
pref start/running, process 2083
# initctl restart pref
initctl: Unknown instance:
# initctl restart pref
initctl: Unknown instance:

# ps uwx
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
afarber   1532  0.0  0.0 108788 15084 ?        S    16:05   0:00
/usr/bin/perl -w /usr/local/pref/pref.pl

#  netstat -an | grep -w 8080
tcp        0      0 0.0.0.0:8080                0.0.0.0:*
     LISTEN

# initctl status pref
pref stop/waiting

Any ideas please?

Thank you
