Hi All,
We have observed already reported zookeeper bug on our WSO2 MB cluster
while testing.
Our setup runs with 4 clustered zookeeper servers {version zookeeper-3.4.5}
.
Issue [1] could be observed on 2,3,4 zookeeper nodes and It seems this
error occurs after the failure of first zookeeper node (due to an unknown
reason). Due to this issue our MB cluster becomes unusable and had to
restart the whole setup.
As per the Zookeper JIRA [2] and [3], observed issue has fixed on the
zookeper version 3.4.0, but we are still obsering this error on
zookeeper-3.4.5 version.
Attached full zookeeper.out file here.
