Hi Lukasz,
I looked at the logs and havent been able to determine how the session
move can happen.
You should go ahead and open a jira for this! Please attach the logs to
that jira. Mark it for 3.3.0 until we can say that it
We've identified the problem and are working on a fix. Full details here:

That is great. Thank you very much for your work!
All the best, Łukasz

JIRA is great because we can move the discussion off the list and track
explicitly along with possible fixes. Also if you create the jira you'll
get updates on any changes to the record (you could 'watch' the JIRA
instead, that's fine too).
Can you include the session id in your client logs?
Hi everyone!
I am writing to this group because recently we are getting some
strange errors with our production zookeeper setup.
From time to time we are observing that our client application (C++
based) disconnects from zookeeper (session state is changed to 1) and
reconnects (state changed to
do you ever use zookeeper_init() with the clientid field set to
something other than null?

nope.
I always pass 0 as clientid.

weird, this does sound like a bug. do you have a reliable way of

Can you verify that you are using 3.2.2 on all servers? You can do this
by running the stat command against each of your servers and look at
the very top of the output (we include the version of zk server there).

We'll probably need the ZK server/client logs to hunt this down. Can you
tell if the MOVED happens in some particular scenario, say you are
connected to a follower and move to a leader, or perhaps you are
connected to server A, get disconnected and reconnected to server A?

Yes, if you search back (older entries) in the server log you will be
able to see who the leader is, it will say something like LEADING or
FOLLOWING, but this may change over time (which is why you need to
search back as I mention) if leadership within the ZK cluster changes

This is very different from most uses of ZK. Normally Zookeeper is used on
a private network with almost no packet loss. Your high rate of loss may be
tickling a protocol bug that other people
just never see.

It will be good to see the logs, however I had one additional thought.
The leader (the zk leader) is the one checking for session MOVED. It
keeps track of which server the session is currently attached to and
will throw the moved exception if the session proposes a request through
a server
Hmm... this inspires me to have a thought as well.
Łukasz, there isn't any fancy network stuff going on here is there? No
NATing or fancy load balancing or reassignment of IP addresses of servers,
right?
