Hi,
I'm using logback in application to log the http request/response into the DataBase (logging_event) table. 
Below given is the Java configuration class for DbAppender.
In my application, I have another configuration class that has some configuration properties and the values of those properties can change dynamically. 
I'm using the @RefreshScope (org.springframework.cloud.context.config.annotation.RefreshScope) annotation to get the new values of the config properties changed on the fly using https://www.consul.io/.
The DBAppender works fine, except that when I make any changes to the configuration properties externally (changing the value of an existing property or adding a new config property in Consul) while the app is running. After I make any changes to a config property externally, the DbAppender will not insert logs into the DB table. These config properties are not related to the logging functionality.

@Configuration
public class LogbackConfiguration {

@Bean
public DBAppender dbAppender(DataSource ds){
   DBAppender dbAppender = new DBAppender();
   DataSourceConnectionSource connectionSource = new DataSourceConnectionSource();
   connectionSource.setDataSource(ds );
   connectionSource.start();
   dbAppender.setConnectionSource(connectionSource);
   dbAppender.start();

LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory();
Logger logger = loggerContext.getLogger("org.zalando.logbook");
logger.addAppender(dbAppender);
   return dbAppender;
}
}

Below given is the configurations related to logging in my application.yml file - 
logbook:
  minimum-status: 100
  exclude:
    - /actuator/**
    - /favicon.ico
    - /swagger-resources/**
    - /swagger-ui.html
    - /webjars/**
logging:
  level:
    org.zalando.logbook: TRACE

Could you please guide me to identify the root cause of this issue?

Thanks
