[Zope] Connection reset by peer - ZServer problem ?

[chas]

Using just ZServer (not apache/pcgi), I've been getting
intermittent "Connection reset by peer" errors. The annoying
thing is that sometimes it happens, sometimes it doesn't.
But it only occurs when submitting forms.

I remember running Netscape webservers a few years back, we
would get the same problem (which was solved when I moved to
Apache). 

Is there some way to  get ZServer to stop doing this or must
I use the Apache/Zope mix instead ?

Thank you,
