>>Hi,
>>
>>I can see now that the problem is not per Data.fs but per object.
>>The problem isnt that 2nd Client to run cant write do Data.fs, I found
>>that its a per object conflict and not Data.fs, both clients can
>>write to the ZSS but once client B writes to object X, Client A will
>>never see the changes neither change the object X, but is capable of
>>changing other objects.
>>
>>Objects changed buy Client B become "locked" for client A and viceversa.
>>
>>Anyone testing ZEO?
