Inizia con la chiamata save di springcloud-lcn-demo DemoController e con i punti di ingresso dello stack trace TransactionServerFactoryServiceImpl.createTransactionServer e NettyServiceImpl. Verifica come la demo raggiunge il server tx-manager e usa i log di connessione riportati per riprodurre il problema. Il lavoro è completato quando la chiamata save termina senza l’eccezione di connessione a tx-manager.
