Indeed, this is caused by the fact you closed STDOUT and STDERR on the
process.

In stead of the -D, you can start Zope up with 

  z2.py [options] Z_DEBUG_MODE=1

where [options] is your current list of options used minus the -D flag.
Zope then will behave demonic again (run nohup) and you'll only miss out
on extra log messages from ZServer.

You might want to add STUPID_LOG_FILE=[path to log] as well, so that
logging messages (like that of the GUF) will be sent to the proper log
file.
