Hello,

I have  implemented server process shutdown via the method invocation method,
i.e.

void
Server::shutdown()
{
... cleanup ...
   spawn thread to run BOA->impl_shutdown();
}

This technique works fine, with the exception that the client throws
COMM_FAILURE.  The server shuts down, but the client aborts (because I am not
handling this exception in this particular case).  If the client has not
performed any method calls prior to the shutdown() call, then no COMM_FAILURE
is thrown.  However, something simple like invoking a method that sends a
IOR back to the client, will cause subsequent shutdown() calls to throw the
exception.  I was under the understanding that spawning a thread in the server
to run the impl_shutdown() is the preferred way, because it allows the client
method call to return.  So what am I missing?

Thanks

Rob

ps.
