[jira] [Comment Edited] (ZOOKEEPER-3769) fast leader election does
not end if leader is taken down

-----------------------------------------------------------------------
After I enabled SASL in order to force the asynchronous creation of sockets, the problem no longer reproduces. Hence I am guessing this might be related to ZOOKEEPER-900

> Could you have a look at the logs and help me figure this out? It seems like node 1 is not getting notifications back from node2, but I don't see anything wrong with the network so I am wondering if bugs like ZOOKEEPER-3756 could be causing it.
