Error Messages

** org.springframework.remoting.RemoteAccessException: Could not access HTTP invoker remote service at [http://<host>:<port>/vbd/service/vbdService]; nested exception is java.io.IOException: Did not receive successful HTTP response: status code = 500, status message = [Internal Server Error]: Could not access HTTP invoker remote service at [http://<host>:<port>/vbd/service/vbdService]; nested exception is java.io.IOException: Did not receive successful HTTP response: status code = 500, status message = [Internal Server Error]

java.lang.IllegalArgumentException: Port value out of range: 65536

Steps to Reproduce

1. Go to Infrastructure > Services.
2. Save and Ping VBD service.

Root Cause

This is a Linux environment specific behavior where VBD can not bind to localhost. JGroups will pick the first non-loopback NIC if the bind address is not specified

Resolution

1. Add a JVM argument to the server running VBD as below (This requires a server re-start):
2. Modify the /etc/hosts file on Linux to include the IP address(s).
