I've got one ZEO instance of Plone 2.5.0 and one ZEO instance of Plone 2.5.3running on one UNIX server. These were both installed using the unified installer for UNIX. I've modified the ZEO ports and also all the ZOPE ports so that there a no conflicts between the two instances. When I access the ZMI in both instances I am seeing Plone sites mirrored between the two instances. Even though the data.fs file for both sit in different areas ....opt/Plone-2.5/zeocluster/.... opt/Plone-2.5.3/zeocluster. What I get is site names etc displayed which haven't been created in that instance and vice versa. When clicking on the site, no actual data is displayed and also skins aren't correct. It also looks like the /Products directories are mirrored in ZOPE. However if I go into site set-up in Plone and add/remove products the correct products are listed for each instance. -- michael
