Hi Folks,
-jail-2.05b$ perl -MPOE -e 'print $POE::VERSION, "\n"' 0.29 -jail-2.05b$
I found a Filedescriptor leek ...
I wrote a FTP-bouncer, a tcprelay with some more functions (identd for example). It forwards only the controll connection, not the data connection. If I connect to the relay, and then disconnect I every time have one more line of this in lsof:
bouncer.p 14586 nick 24u sock 0,4 864749 can't identify protocol
This increases and increases, on each connect/disconnect, and then some object dies (only one of the socketfactories) with too many open files. The thing is, if I remove the following line, this doesn´t occure:
$kernel->detach_myself();
What is false to use this to detach object from the parent object? It is needed for the reinit of the config, for not terminating the open connetions. Must I then do things myself for destroying SocketFactories?
Debuginformation:
xx1-xx-xxx-xx is IP of Server, xx2-xx-xxx-xx is IP of Targetserver and xx3-xx-xxx-xx is IP of Client. The files /beforeall, ./connected, ./disconnected, b2.cfg and the script itself are attached.

-> I´ve one more open file descriptor between beforeall and disconnect!
