Hi Remo,

Thanks.  Tenzin, does AMQ-4882 seem like your issue?

Hi Remo,

FYI: seems like AMQ-4882 talks about a problem that occurs in a replication cluster.

> I have clustered 3 ActiveMQ instances using replicated leveldb and zookeeper. When performing
some tests using Web UI, I can across issues that appears to corrupt the leveldb data files.
> The issue can be replicated by performing the following steps:
> 1.	Start 3 activemq nodes.
> 2.	Push a message to the master (Node1) and browse the queue using the web UI
> 3.	Stop master node (Node1)
> 4.	Push a message to the new master (Node2) and browse the queue using the web UI. Message
summary and queue content ok.
> 5.	Start Node1
> 6.	Stop master node (Node2)
> 7.	Browse the queue using the web UI on new master (Node3). Message summary ok however
when clicking on the queue, no message details. An error (see below) is logged by the master,
which attempts a restart.
> From this point, the database appears to be corrupted and the same error occurs to each
node infinitely (shutdown/restart). The only way around is to stop the nodes and clear the
data files.
> However when a message is pushed between step 5 and 6, the error doesn’t occur.
> =================================
> Leveldb configuration on the 3 instances:

> 					directory="${activemq.data}/leveldb"
> 					replicas="3"
> 					bind="tcp://0.0.0.0:0"
> 					zkAddress="zkserver:2181"
> 					zkPath="/activemq/leveldb-stores"
> 					/>
