Something is clearly wrong with your build of it then.

This is omniORB's normal way of handling a connection being closed. It
throws the internal giopStream::CommFailure exception and catches it
higher up the call chain.

But this shows that the exception handler didn't trigger. The problem
is not in omniORB, but something about the way it was compiled.

Clearly that is not the right thing to do. The code throws the
exception on purpose. If you break the code by no longer throwing the
exception, the server will no longer properly clean up connections.

You need to figure out why your build broke the exception handling.

You haven't mentioned what platform you are using.
