When you start it via the initscripts (/etc/init.d), are you doing as
the root user or as an unprivileged user? I'm suspecting a permissions
issue here in that the threads (actually lightweight processes) are
being run as different users.
You might try using "ps uax -L" and looking at the various threads
involved to see who's running what.
