BindException when deploying

[ksimpson]

Seeing the following error from Jetty when deploying application bundle:

10:39:59,773 | ERROR | NAPSHOT-thread-1 | BlueprintCamelContext            | 138 - org.apache.camel.camel-blueprint - 2.10.0.redhat-60024 | Error occurred during starting Camel: CamelContext(portland-esb-context) due Address already in use

java.net.BindException: Address already in use

Environment

•   Four active Fuse ESB containers, two each on pair of VMs
•   All four containers are active; their AMQ brokers contend for lock on NFS
•   Deployment consists of FTP'ing application bundle into each container's deploy folder

There are only three Jetty endpoints with corresponding from() in the application, defined in properties file (all resolve ok):

1. cad.acceptor=jetty:http://0.0.0.0/cad/CADService
2. {{cad.acceptor}}/echo
3. jms.acceptor=jetty:http://0.0.0.0/jms/JMSService

Note that 'echo' endpoint is extension of 'cad' endpoint.  Also, all endpoints use default port, 80.

Can multiple Jetty endpoints use the same host (0.0.0.0) and port combinations?  What else could be causing BindExceptions?

Thanks!
