[omniORB] call to _non_exist

[Andreas Eglseer - Entwicklung]

I want to check , if the client, that registered at my server has died or
not.
I tried it in the following way:

I wrote a funtion, that I start with the omni_thread::create method, the
function looks like:

#define CHECK_TIME 10

void check_client(void* arg)
{
   int failed_calls = 0;
   int chk;
   while(failed_calls < 3)
   {
     omni_thread::sleep(CHECK_TIME);
     try
     {
       chk = chkClient->_non_existent(); // chkClient is a global Variable
     }
     catch(...)
     {
       cerr << "Exception occured while trying to check client\n";
       failed_calls++;
     }

     if(chk)
     {
       cerr << "Checking client failed\n";
       failed_calls++;
     }
     else
      cerr << "here\n";
   }
  boa->impl_shutdown();
   cerr << "BOA Shutdown retrned";
}

Normally I get an exception and after 3 tries the program ends, but
sometimes the call to _non_existent is hanging.
Is there a better way to check, if the client app is alive, or could you
please tell me why it is possible that the _non_existent call
hangs.

Thank's for your help.
