Hi all,<br><br>I have a curious bug that I've tracked down to a call to gen_tcp:controlling_process.  From the stack trace (simple example reproduced below) it seems that the port in question definitely exists, but the call to inet_db:lookup fails.  Has anyone seen this before or got any advice?<br>
