      ADDITIONAL SYSTEM INFORMATION :

      A DESCRIPTION OF THE PROBLEM :
      Lot many threads are in RUNNABLE STATE and doesn't come out in
        java.lang.Thread.State: RUNNABLE
              at java.net.Inet4AddressImpl.lookupAllHostAddr(java.base@11.0.8/Native Method)

              at java.net.InetAddress$NameServiceAddresses.get(java.base@11.0.8/InetAddress.java:832)

      REGRESSION : Last worked in version 11

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      When ever we get an DNS Resolution issue which throws UnknownHostException after some time the threads are getting blocked and we need to restart the system

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The system should not be paused or blocked and once the DNS resolution is proper the system should become stable

      FREQUENCY : often
