  It is a good idea for the caller to check the main trace TraceComponent.isAnyTracingEnabled() before calling this method.
  
  The data output by this message can be searched for in several ways:
  
  <nl>
  <li>Searching on JFAPSUMMARY will output all segments sent and received</li>
  
  <li>On a per connection basis. This is done by doing a search of the form "[client dotted ip address:client port number:server dotted ip address:server port number".
  This information is displayed the same on the client and server side of the connection and so can be used to match up client and server traces</li>
  
  <li>On a per conversation basis. This is done by doing a search of the form "[client dotted ip address:client port number:server dotted ip address:server port number:conversation id".
  This information is displayed the same on the client and server side of the connection and so can be used to match up client and server traces</li>
