[omniORB] A strange IP address appear in omniORB log

[jianping jia]

Hi,
I have one distributed application that run on two servers(port 66666 is
defined for INSPOA). Always, it cannot continue communication after a time
period of normal running.
OmniORB log is collected as follows:

Appreciate if any one can tell me what cause the problem.
I suspect something like connection leakage cause the correct port cannot
be used, but what can cause that? Besides, why a strange IP address
172.50.10.102:6666(the IP of two servers are 172.50.10.1 and 172.50.10.2
respectviely) appears when error occurs?
Any help is appreciated.
Thank you very much.

Best Regards
Jia Jian Ping

[Mayo, Jeff]

In IP v4, TCP port addresses should be 16 bit unsigned integers, i.e.
65535 or lower. I'm not sure what the OmniORB server code will do with
your port address of 66666.

Appreciate if any one can tell me what cause the problem.
I suspect something like connection leakage cause the correct port
cannot be used, but what can cause that? Besides, why a strange IP
address 172.50.10.102:6666(the IP of two servers are 172.50.10.1 and
172.50.10.2 respectviely) appears when error occurs?
Any help is appreciated.
Thank you very much.

Sorry, I mistyped the number. It should be 6666. Thanks

Post by Mayo, Jeff
In IP v4, TCP port addresses should be 16 bit unsigned integers, i.e.
65535 or lower. I?m not sure what the OmniORB server code will do with your
port address of 66666.

What version of omniORB are you using?

It looks as though you are referring to your server by name. Does the
name resolve to 172.50.10.102 as well as 172.50.10.1? Alternatively,
where does the object reference for the server come from? An object
reference can contain more than one address.

The TRANSIENT_ConnectFailed exception means the opening a TCP connection
failed. What is happening on the server at the time the error occurs?
Normally connection failures are due to the server no longer listening.

Cheers,

Duncan.

Hi Duncan,
Thank you for replying. We are using OmniORB 4.0.5. As you suspected, we're
using server name for resolution. The reference is directly gotten via
string_to_object() and string is formatted as
"corbaloc::giop:servername/identifier". Besides what I mentioned in the
previous email, there is also one strange thing that restarting client can
continue to get communiation with server after the communication fails, so
it should be not due to the server no longer listening. Any issue in client
can cause such error even if the server is listening for connection?
Another strange thing is that two servants in the same server that can be
accessed via INSPOA behave differently. Sometimes, only one of them can be
accessed, while the other one can only get the transient_connectfailed.
Thanks
Best Regards
Jia Jian Ping
