Jeremy,
I re-read what i posted earlier and need to make an important, i think,
clarification.  Its more likely to happen that only one or the other
public site will not get updated.  That is the user edits content on
private admin site, submits it, then the content is updated on public
zeo client 1 but not on public zeo client 2 (or vice-versa).  Of the
cases where this has occured in the past 3 months, the majority is that
only one public zeo client gets updated.  

the physical layout of the network is:
3 zeo clients behind a firewall with only ports open to allow ssh, and
web required ports (80, 443, realserver, etc).

1 zope storage server behind a firewall that only allows connections
from the 3 zeo boxes.  only those ports required for zeo are open

You cannot directly connect from the Internet to the zope storage server
box.

regarding the logs: we don't have the verbose mode on and cannot restart
the server until at least 9:30pm EST because its live.  we will attempt
to reproduce the problem.
