Well, it should be the same if syslog-ng gets the same command line
arguments. Are you sure that they are the same if you start manually or
by the system boot process?

As Sandor has said, the --process-mode option (or -F for that matter)
influence how syslog-ng itself is managing its own run. (whether to use
a supervisor or not).

Also the PID file that syslog-ng writes contains the PID of the 'real'
syslog-ng and not the supervisor. The supervisor exits if the real
process is terminated normally.

So you can check what's in the pidfile, that's the syslog-ng actually
doing work.

On Linux, syslog-ng changes the process name to contain whether it is a
supervisor or not, but I guess that hack doesn't work on HP-UX.
