All right, here the traceback produced by the zeo server, thanks for helping!:

Alas, the traceback doesn't really help.  You're showing a traceback from the ZEO client, but zrpc is just (re)raising an exception passed _back_ to it by the ZEO server.  You may be able to find a useful traceback in your ZEO server log file.

My production site works with 2 ZEO-clients.
Following error occurs while attempting to pack the 
ZODB (same error with zope-2.7.7):

Traceback (innermost last):
