Fabric very instable when insights is deployed

Here is what I have deployed in jboss-fuse-6.2.0.redhat-046

JBossFuse:karaf@root> fabric:container-list
[id]   [version]  [type]  [connected] [profiles]                       
[provision status]
root*  1.0        karaf   yes fabric                           success
                                        fabric-ensemble-0000-1
                                        jboss-fuse-full
                                        insight-camel
                                        insight-console
insight-metrics.elasticsearch
                                        example-camel-twitter
                                        insight-logs.elasticsearch
insight-elasticsearch.datastore
                                        insight-elasticsearch.node

The behavior is really strange. After a certain period of time (I was 
absent from my desk & machine for 2 hours), fabric is gone

JBossFuse:karaf@root> fabric:
fabric:archetype-generate     fabric:archetype-info 
fabric:archetype-list         fabric:archetype-workspace 
fabric:create                 fabric:crypt-algorithm-get 
fabric:crypt-algorithm-set
fabric:crypt-password-get     fabric:crypt-password-set 
fabric:encrypt-message        fabric:join fabric:welcomeld

and these errors appears in the log
