Corba Naming_Service creates so many UDP connections

Question

The Corba Naming_Service creates so many UDP connections and they are still remained even when the clients are disconnected. It goes up to 60K connections.

AIX 5.3, TAO Version 1.5a_p22 and ACE Version 5.5a_p22

Below is the losf:

Naming_Se 692382 slist  319u  IPv4 0xf10006000f914200             0t0    UDP *:*

Where/How to solve this problem?

Thank you.

Answer 1

The problem is that AceTao Naming_Service creates new UDP sockets when it is connected and leaves as dump even when client disconnects it. I think that is the bug in ACE5.5 TAO1.5. Upgrading to ACE5.6 TAO1.6 p13 solved the problem.
