Subject DO NOT REPLY [Bug 46461] New: fail graceful on dns changes for connectors/hosts in server.xml
Date Thu, 01 Jan 2009 15:25:46 GMT
https://issues.apache.org/bugzilla/show_bug.cgi?id=46461

           Summary: fail graceful on dns changes for connectors/hosts in
                    server.xml
           Product: Tomcat 6
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Catalina
        AssignedTo: dev@tomcat.apache.org
        ReportedBy: hauser@acm.org


in a server.xml,
there are n > 4 connectors declared on a physical machine with multiple ip
addresses.

Due to a dns change, connector 2 and connector 3 end up with the same ip
address.

This rightfully causes connector 3 not to get up and running with
ERROR [main] (Catalina.java:553) - Catalina.start:
LifecycleException:  service.getName(): "HTTPSmyApp3";  Protocol handler start
failed: java.net.BindException: Address already in use:8443

org.apache.catalina.core.StandardServer.start(StandardServer.java:709)

        at java.lang.reflect.Method.invoke(Method.java:585)
        at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:294)
        at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:432)

However, all subsequent connectors 4..n will not start either - isn't a
dns-misconfiguration having too big effect on a mostly correct server.xml
config?
