This is harmless -- some network problem caused the client connection
to get broken.

This is deadly. Zope can no longer accept any connection.

I have seen this on Solaris and I blamed this outdated OS
because the error returned by "accept" could not be raised
according to the Solaris documentation ...
I assumed that Solaris got some internal resource shortage.


There may be an alternative reason: your process has run out
of file descriptors. Check the limit ("ulimit -n").
