URL: https://github.com/apache/skywalking/issues/6064#issuecomment-1764140331

   Which version of SkyWalking, OS, and JRE?
   
   skywalking 9.0.0 thrift 0.14.1
   
   Which company or project?
   
   cisdi-info
   
   What happened?
   A large number of NoopExitSpans are being generated in the application stack and not being released, resulting in a memory overflow within the application.
   
   Object dynamicField = ((EnhancedInstance) protocol.getTransport()).getSkyWalkingDynamicField();
   The exception message is
   java.lang.ClassCastException: org.apache.thrift.transport.TFramedTransport cannot be cast to org.apache.skywalking.apm.agent.core.plugin.interceptor.enhance.EnhancedInstance
   
   Catching this here would eliminate the error, but I'm not sure if it would cause other issues
               try {
                   Object dynamicField = ((EnhancedInstance) protocol.getTransport()).getSkyWalkingDynamicField();
                   objInst.setSkyWalkingDynamicField(Objects.isNull(dynamicField) ? "UNKNOWN" : dynamicField);
               }catch (Exception ex){
                   objInst.setSkyWalkingDynamicField("UNKNOWN");
               }
