That's wierd. daemonize must be doing something odd in RH9.
start-stop-daemon (Debian) doesn't show this problem:

10694 ?        S      0:01 /usr/sbin/spamass-milter -p
/var/run/sendmail/spamass.sock -u user
10695 ?        S      0:01 /usr/sbin/spamass-milter -p
/var/run/sendmail/spamass.sock -u user
10696 ?        S      0:00 /usr/sbin/spamass-milter -p
/var/run/sendmail/spamass.sock -u user


Daemonize is a shell script. You can't become a proper daemon from a shell 
script. The steps to be taken are very well defined:

* Double fork.
* Close all descriptors.
* Call setsid()
* Set signal handlers so you don't get inherited handlers.
