Camille Fournier commented on ZOOKEEPER-1955:
---------------------------------------------
It looks like the problem may actually be in the log file, from your report:
2014-07-04 12:58:52,896 [myid:1] - DEBUG [main:FileTxnLog$FileTxnIterator@575]
- Created new input stream /var/lib/zookeeper/version-2/log.300000021
2014-07-04 12:58:52,915 [myid:1] - DEBUG [main:FileTxnLog$FileTxnIterator@578]
- Created new input archive /var/lib/zookeeper/version-2/log.300000021
2014-07-04 12:59:25,870 [myid:1] - DEBUG [main:FileTxnLog$FileTxnIterator@618]
- EOF excepton java.io.EOFException: Failed to read
/var/lib/zookeeper/version-2/log.300000021
I can load a ZK fine with the snapshot you've provided. Do you have the log
file or other data?

> Key: ZOOKEEPER-1955
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1955
> Project: ZooKeeper
> Issue Type: Bug
> Affects Versions: 3.4.5
> Reporter: Aaron Zimmerman
> Attachments: snapshot
>
>
> We have a 5 node zookeeper cluster that has been operating normally for
> several months. Starting a few days ago, the entire cluster crashes a few
> times per day, all nodes at the exact same time. We can't track down the
> exact issue, but deleting the snapshots and logs and restarting allows the
> cluster to come back up.
> We are running exhibitor to monitor the cluster.
> It appears that something bad gets into the logs, causing an EOFException and
> this cascades through the entire cluster:
