The customer has observed that in the flow of "undeploy" and "deploy" modules they open a jvisualvm/jconsole to the JMX node to check the data of the caches and cache services. Then they perform a suspendService of services. Then they perform undeploy of APP modules and DATA module. When undeploy of the modules has finished, if they consult in jvisualvm/jconsole to verify whether the services are not active, they still see that in the services tab, it still maintains the services. The procedure they follow for the redeployment is :Suspend storage enabled services->Undeploy->Resume storage enabled services -> Deploy modules: however, intermittently they see data loss.
