             Summary: client session expired after timeout after errors and warning logs in
zk server logs
                 Key: ZOOKEEPER-3435
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3435
             Project: ZooKeeper
          Issue Type: Bug
    Affects Versions: 3.5.1
            Reporter: prashant


Hi

We use 3.5.1-alpha version.

We are seeing session expiry issue in VM set up.

This is running in replicated more (two servers + node mastership as one vote for quorum).

we see client session expired after session timeout (of 10 sec).

This connection was to local zk server. session timeout is 10 sec.

This session got established at 17:40:18 and ZK server expired this at 17:40:57, after 39
seconds of establishment.

in between this time, i see few errors and warnings in zookeeper server logs (as shown below).

I see below errors/warning in between this time before session expiry.

This issue is not very easy to replicate , so far we have seen only twice.

Could you please help me identify root cause and let me know if this is fixed in later release
? Thanks, Prashant
