             Summary: Couchbase client is never shut down
                 Key: CAMEL-11674
                 URL: https://issues.apache.org/jira/browse/CAMEL-11674
             Project: Camel
          Issue Type: Bug
    Affects Versions: 2.20.0
            Reporter: James Netherton


I'm testing couchbase while it's running within a container (WildFly). If my camel-couchbase application is terminated, I still see client connections being attempted. I guess there's a background thread that's still operational.

The client has a {{shutdown()}} method, so we should probably make use of that somewhere.

Server logs are full of errors like:
