title: WSO2 waiting for required OSGI services during startup
body: <p>I'm running WSO2 AM 1.10.0 in cluster node on two virtual machines on my PC (one acting as manager node the other is a worker node). Recently I had to re-install my PC from scratch with Windows 10, and occasionally after restart I receive the following warning messages repeating again and again:</p>
  
  <pre><code>WARN {org.wso2.carbon.application.deployer.internal.AppDeployerServiceComponent} 
     Waiting for required OSGi services: 
         org.wso2.carbon.application.deployer.synapse.service.SynapseAppDeployerService,
         org.wso2.carbon.mediation.initializer.services.SynapseEnvironmentService,
  WARN {org.wso2.carbon.core.internal.StartupFinalizerServiceComponent} 
     Waiting for required OSGi services: 
         org.wso2.carbon.application.deployer.service.CappDeploymentService,
         org.wso2.carbon.server.admin.common.IServerAdmin,
         org.wso2.carbon.throttling.agent.ThrottlingAgen,
  </code></pre>
  
  <p>It does not happen each time, but when it happens it does not allow WSO2 to start for a long time. Any possible reason why it happens?</p>
