Then perform the below steps to confirm the same. 1. Click on the managed server from Environment-> servers. 2. Go to Health tab under Monitoring tab as shown in the below figure. 3. Here we can check the health of each deployment file on this managed server. We can see 3 stuck threads on ConsumerPortal_EAR deployment as highlighted below.
