Resolution: Cannot Reproduce
> JMX not reliable - MBeans deleted
> ---------------------------------
>
> Key: SOLR-2344
> URL: https://issues.apache.org/jira/browse/SOLR-2344
> Project: Solr
> Issue Type: Bug
> Environment: linux 64bit x86_64
> java version "1.6.0_13"
> Reporter: Matthew Sporleder
> Labels: jmx
>
> I am using JMX to monitor my replication status and am finding that my
> MBeans are disappearing. I turned on debugging for JMX and found that
> solr seems to be deleting the mbeans.
> This appears to be a triggered event, but I am not finding any clues as to why this is happening.
> Is this a bug? Some trace info is below..
> here's me reading the mbean successfully:
> Jan 27, 2011 5:00:02 PM ServerCommunicatorAdmin reqIncoming
> FINER: Receive a new request.
> Jan 27, 2011 5:00:02 PM DefaultMBeanServerInterceptor getAttribute
> FINER: Attribute= indexReplicatedAt, obj=
> solr/myapp-core:type=/replication,id=org.apache.solr.handler.ReplicationHandler
> Jan 27, 2011 5:00:02 PM Repository retrieve
> FINER: name=solr/myapp-core:type=/replication,id=org.apache.solr.handler.ReplicationHandler
> Jan 27, 2011 5:00:02 PM ServerCommunicatorAdmin reqIncoming
> FINER: Finish a request.
> a little while later it removes the mbean from the PM Repository
> (whatever that is) and then re-adds it:
> FINER: Send create notification of object
> solr/myapp-core:id=org.apache.solr.handler.component.SearchHandler,type=atlas
