This is not true. OmniORB always sends a GIOP CloseConnection message when
it closes a connection. 

If you are not convinced, try telnet to the BOA port and leave it idle for
a few minutes, when the server closes the connection because it has been
idle for a period of time, you can see in your telnet session that the
server has sent a GIOP close connection message before it close the
connection.

e.g.

On host neem:

$ ./eg2_impl -BOAiiop_port 12345 &
$ telnet neem 12345
Trying 158.124.65.37...
Connected to neem.uk.research.att.com.
Escape character is '^]'.
GIOP  Connection closed by foreign host.
^^^^^^

I'm afraid MICO has to look into why it is not doing a reconnection.

The management of idle connections can be controlled in omniORB, please
refer to the user guide for details.
