We are using ACE+TAO 2.0a in our project and facing following
issues in one of the customer production.<br>

1. We are setting following debug options in orb_init at server

seen. At the client side we only see ACE traces and not the TAO traces.<span></span></span></p>

2. We are using </span><span style="font-size:10pt;font-family:"courier new"">BIDIRECTIONAL
port usage in our Server and Client application for communication. Two thread
are being used at server side to Communication with client. One thread is uses
a callback of client to send the actual data, second thread calls client
callback for polling mechanism . When everything is going fine both the threads
at server use 6001 to communicate with client. But suddenly polling thread
callback request from the server will be sent to client on different port ( Ex
: 52345). After this connection is lost between the server and client. After
analyzing the pcaps it is confirmed that signature remains for all the
disconnections and RST( at TCP Level) is received from the client for request
on port 42345. Even though BiDirectional is set why the request is going on new
port. Server and client are multithread application.</span><span style="font-size:9.5pt;font-family:arial,sans-serif"><span></span></span></p>
