TID: [0] [STRATOS] [2014-08-11 23:34:03,345] ERROR {org.apache.stratos.manager.m anager.CartridgeSubscriptionManager} - No active instances are found for cartri dge [centos] {org.apache.stratos.manager.manager.CartridgeSubscriptionManager} Im using Statos 4.0.0 with docker in an image EC2 in the cloud. i follow the source code and found this method private boolean activeInstancesAvailable(SubscriptionData subscriptionData) { Cluster cluster = TopologyClusterInformationModel.getInstance().getCluster(subscriptionData.getCartridgeType()); int activeMemberCount = 0; if(cluster != null) { Collection<Member> members = cluster.getMembers(); for (Member member : members) { if(member.isActive()) { activeMemberCount++; } } } if(log.isDebugEnabled()) { log.debug("Active member count for cluster [" + cluster +"] is : "+ activeMemberCount); } return activeMemberCount > 0; } can you explain me more about this or give me an example to configure multitenant cartbrige. im from Argentina sorry is my english is note clear, let me know. PD: Also when i try to subscribe a multitenant cartbrige without add a load balancer gives me NPE i thinks there is a bug there.
