[Zope] ZODB.POSException.ReadConflictError

[Christopher N. Deckard]

I get errors like this a lot:

Error Type: TALESError                                              
 file Error Value: ZODB.POSException.ReadConflictError on database
read      :   conflict error (oid 000000000013d150, class
BTrees.IOBTree.IOBucket)  pic0 in "", at line 48, column 17    

I have a script that queries a ZCatalog and returns the list from
the query.  There are about 2,000 objects cataloged.  The objects
are ZCatalog aware, so they auto-update the catalog when changed. 
Whenever this is happening during the query, I get the
ReadConflictError.  

I'm using ZEO on a single machine.  I've tried with multiple ZEO
clients, but still get the same results.  Is there anything I can do
in my Product to prevent this from happening?  Maybe something else
I can configure?

Thanks,
-Chris
