IBM AIX tcp port opens twice when initiating a connection as part of an interface

[msxi]

Hi All,

Perhaps somebody could be of assistance. We have an issue where when we make a connection to a tcp port as part of a tcp socket interface two connections to the port is being established. The result is that when sending the initial helo we're receiving data from the second connection. Is there a way we can restrict the port to only open one connection to it rather than two?

Please forgive my lack of knowledge in this field. Any advise that can be shared will be highly appreciated.

Thanks
