4. Enable Hostmap Debugging

	Warning
	Changing the rootLogger value from ERROR to DEBUG generates a large amount of debug logging.

Enable additional logging by editing the gateway-log4j.properties file in the directory.

Edit the $gateway_home\conf\gateway-log4j.properties gateway-log4j.properties file.
Change ERROR to DEBUG on the following line:
```
log4j.rootLogger=ERROR, drfa
```

Restart the gateway:

cd $gateway_home
bin\gateway.cmd stop
bin\gateway.cmd start
