Flavio Junqueira commented on ZOOKEEPER-335:
--------------------------------------------

Radu, It sounds like the problem you mention has been resolved in 
ZOOKEEPER-790. I'm not sure which version you're using, but perhaps you should 
consider moving to 3.3.2.

> zookeeper servers should commit the new leader txn to their logs.

> currently the zookeeper followers do not commit the new leader election. This 
> will cause problems in a failure scenarios with a follower acking to the same 
> leader txn id twice, which might be two different intermittent leaders and 
> allowing them to propose two different txn's of the same zxid.
