You could try running the listener in trace mode to see if the trace output reveals anything.

ORACLE> lsnrctl
LSNRCTL> trace 9

It should tell you that the trace file was opened and that it will be found in $ORACLE_HOME/network/trace/listener.trc. Use the command trace 0 to turn it off again as you get loads of info. I don't know what the various trace levels mean so just dump it all. It may not help but then again....

I have seen GIOP connections where the listener accepts the connection OK on port 2481 but is not able to resolve the database connection part of the sess_iiop string into a database name.

"Lost connection" sounds like TCP related message - you're not running through a firewall or anything like that are you?

Good luck
