[Ace-users] [ace-users] Getting a TCP socket connection with a unique port perthread

[Jim Hodapp]

Steve, thanks for the reply. I have resolved my issue and it ended up  
being a problem that resulted from something I failed to notice,  
completely unrelated to ACE. I hate it when that happens. I do have a  
unique instance for tcpStream and am now getting unique TCP  
connections per each thread.

Thanks,

Jim
