Various versions of ZEO have had bugs in the invalidation propagation. 
I think there are a few unit tests for it now, though, so I'd be 
surprised if it's popping up again.  Perhaps you're running an older 
version of ZEO.  ZEO is no longer distributed separately--use the ZEO 
package from ZODB 3.1.2.  I don't know what version of ZODB corresponds 
with ZEO 2.0.1b1.
