[Zope] Restart causes "Module ZPublisher.Publish, line 98, in publish"

[Jimmy]

Hi List,

I am new to the whole zope world, so I'm sorry if this is a real newbie
question.  :)

I have zope setup and everything seems to be working OK.  except for 2
things.  Someone developed a zope product that I installed on the server
that produces errors and in the control panel when I try to restart the
zope server I get an error page.  
When I check the error log, I get this traceback when I try to restart:

Traceback (innermost last):
  Module ZPublisher.Publish, line 98, in publish
  Module ZPublisher.mapply, line 88, in mapply
  Module ZPublisher.Publish, line 39, in call_object
  Module App.ApplicationManager, line 327, in manage_restart
  Module zLOG, line 130, in LOG
  Module ZLogger.ZLogger, line 16, in log_write
  Module ZLogger.stupidFileLogger, line 27, in __call__
  Module ZLogger.stupidFileLogger, line 90, in stupid_log_write
IOError: [Errno 5] Input/output error

And the errors with the product start the same way, so I think it may be
the instalation of Zope or permissions that are set wrong.  Any ideas
where I can start looking to fix this? 
(BTW, I can restart it from the command line.)

I don't know if any of the following is relavent or not, but I figured
it can't hurt to include it.  

This is the debug info:
