[ZODB-Dev] Disconected Error

[Alastair Burt]

I keep getting Disconnected Errors with my ZEO. They always arise when I
use the undo tab in the ZMI. I see from searching the mailing lists that I
am not the only one to experience these errors arising from undo
behaviour. But, as far as I can see, there is no indication in the list
archives of the root cause of this problem and how to get around it. When I
mount the Data.fs directly, without using the ZEO, there is no problem. Can
anyone tell me what is going wrong?

My system configuration is:
  
  Zope Version: (Zope 2.6.1 (source release, python 2.1, linux2), python 2.1.3, sunos5)
  ZEO: 2.0.1b1
  Python Version: 2.1.3 (#2, Aug 31 2002, 19:15:40) [GCC 2.95.3 20010315 (release)]
  System Platform: sunos5
