[Zope] Wierd startup problem

[Shaw, Howard]

I have Zope 1.10.2 and ZAP. Occasionally, when I restart my machine, ZAP
starts, but when connected to, reports that "A Serious Application Error
has occurred". If I then stop the ZAP server, start the ZopeHTTPServer,
stop the ZHTTPS and restart the ZAP server, it works normally. 

Does anyone know why it would do this, or what I can do to correct it? I
could put in the startup script a kludge to perform the start/stop/start
but I would rather figure out what the problem is and correct it.

Thank you.
