[omniORB] Issues with persistent objects

Hi,
I created a persistent object using omniINSPOA and setting the endPoint
parameter suitably.
The object is persistent as I get the same IOR when the server restarts.
Now, when the client calls a method after a server restart, a COMM_FAILURE
exception
is raised. The interesting thing here is that when the client catches the
exception and issues
another call to server, the server method is executed.
So, basically only the first call after the server restart raises an
exception. All calls henceforth
works fine.
if the below code is executed after server restarts.
try {
return obj_ref->send_book(the_book, key); // this raises an exception
}
catch(...) {
cerr << "Exception Caught" << endl;
return obj_ref->send_book(the_book, key); // this call works fine
}
In the above code send_book is the server method called by the client.
