[omniORB] 2nd invocation in case of timeouts

[Masaaki Sekiya]

Hello.
I'm using omniORB 3.0.2 on HP-UX11.00.
When a client invokes server object method with -ORBclientCallTimeOutPeriod,
( which not to return for long time )
a server object method seems to be invoked twice.
2nd invocation seems to be on the time that client timeout is expired.
A few seconds after 2nd invocation occured,client catches COMM_FAILURE.
Is this a right action ?

And one relevant question.
Is there any way to distinguish COMM_FAILURE because of timeout 
and other reasons ?

Thanks in advance.
