Symptoms:
Unable to connect to JMX. Error "java.rmi.server.ExportException: Port already in use: 555; nested exception is: java.net.BindException: Permission denied".
Cause:
The is because JMX port number 555 was configured with the engine.

"java.net.BindException: Permission denied" exception occurs when APIX engines connect through JMX.

Opening a JMX port number below 1024 requires root privileges. Unix based systems declare ports < 1024 as "privileged" and admin rights/ root privileges are required to start a service. This issue can be resolved by using a JMX port number greater than 1024.
