[ZODB-Dev] Zope 2.8.1 w Zeo 3.4.1 fails where standalone Zope 2.8.1 works

[Erik Lundh]

I have used Zeo with Zope 2.7.6 for some time now.
I currenty run Plone 2.05 on Zope 2.7.6 with zeo in production. Zope and Zeo
runs on the same
machine running Debian Linux 3.0 (i386).
I started using zeo to make debugging of a simple skin product easier.

Now I am moving to a fresh server w Debian Linux 3.1 where I am trying the
same setup with Zope 2.8.1.

Zope 2.8.1 with Zeo 3.4.1 fails utterly.

I can some times get instances running but eventually get transactions
failures, lost connections, and poskeyerrors.

It seems like smooth sailing when I run Zope 2.8.1 standalone.

But when I try to set up, from scratch, a split Zope 2.8.1/Zeo 3.4.1 I get
poskeyerrors, transactions that fails, etc.

I always clear out all things zope and reinstall zope from scratch. I only
use the code in Zope-2.8.1-final.tgz

Below is my setup and remove scripts
The resulting zope install works fine as long as I use a zope.conf for
standalone Zope.

Another fishy thing is that zeo fails to start when you uncomment the line
#user zope
in zeo.conf

Are there any additional test suites that I can run to nail down my problem?
I did run the standard make tests in Zope 2.8.1 with no failures.
