org.apache.coyote.tomcat5.MapperListener init -> Error registering contexts -> HTTP
1.1 connectors pauses

           Summary: org.apache.coyote.tomcat5.MapperListener init -> Error
                    registering contexts -> HTTP 1.1 connectors pauses
           Product: Tomcat 5
           Version: 5.0.27
          Platform: Other
        OS/Version: AIX
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: Connector:Coyote
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: emailtodidi@gmx.ch


Tomcat with two Services each with one HTTP1.1 Connectors and one AJP-Connector

Service A for administration (/admin) of Tomcat/doku etc.
with one HTTP1.1 connector (Port 8080) for administration of Tomcat

Service B for the webapplication
with one HTTP1.1 connector (Port 8081) for manager (/webapplication/manager) of
webapplication, so that developpers can stop/start, deploy/undeploy the
webapplications
one AJP-connector for communication with apache over mod_jk2

When the server starts, all seems good right up until the end of the Tomcat 
startup where the following exception is thrown:

This causes the specific connector to "pause"

This happens accidentally. Sometimes both HTTP connectors pauses sometimes only
the first sometimes only the second. I had to restart Tomcat more than 10 times
until it starts without failure.

When it starts without failure the "org.apache.coyote.tomcat5.MapperListener
init" is not executed.
