[Zope] restart from the control pannel ... not restarting

I've installed Zope 2.6.0 from source on a linux box (SuSE 7.2). Everything runs fine except it does not restart from the control panel. I'm sure this must be some privilege issue. I am starting Zope as the root user and running Zope (./start -u brad) as just a normal user. Any ideas why it might not be restarting automatically? Is there a log file I can go to to see what exceptions might have been raised?? Thanks in advance.
