Samuel Just updated ZOOKEEPER-3253:
-----------------------------------
Description:
Once the cxid value increments to -4, the client will interpret the response as
an auth packet rather than as a response to a request and will transparently
drop the response and the request will hang. Similarly, -2 will be seen as a
ping and will be dropped hanging the request. -1 shows up as a WatcherEvent
and results in the error below.
