There is not much to advise or say. FOP2 is event based and will react as soon as an event is processed. My suggestion is to use the special user as described in the documentation, same as I said before. Use a special fop2 user, with eventfilters to reduce manager output, and not the overcrowded admin user. You can also try to catch me on the live help at www.fop2.com and provide remote ssh access to your server to verify your setup.
Best regards,
