Hallo,
I am trying to install a setup like shown below
ZEO_M
| -- ZEO_B
| | -- ZOPE
| | -- ZOPE
| | -- ZOPE
| ...
| -- ZOPE
| -- ZOPE
...
The ZEO_B should be a zeoclient of the ZEO_M (MainZEO). The reason for
this setup ist that the ZEO_B is located in a backup computing center on
the other side of our campus.
When I configured the ZEO_B as a zeoclient of the ZEO_M. I comes up
without problem. I've connected the first client, the connection is
establisched but the server never come up.
Here is the log from ZEO_B level debug

I started it with runzope and killed it with CRTL-c. I had it once waiting for
2 hours without any difference.
here is the ZEO_B config file

The Zope Server directly on ZEO_M works without problems.
