Please remove my question! I changed loglevel to warning, that’s why I got the warnings in logfile. So, seems that its just an information that IPv6 addresses can not be bound.

Thanks

Hi,

Since a few days I have the problem that clients do not get events forwarded from our server. It seems that it tries to send a few events and then breaks.

I figured out following entry in log-file:

BindingFactory:toBindNames – Binding of opc.tcp://localhost:4840 to 0:0:0:0:0:0:0:1 was omited (Workaround) same entry found for DNSname too!

It is flaged as being a warning. What does it mean and would this break processing my events? I haven’t had the issue before. System is running now for about 1 year.

Thanks for your help

The issue described above, now, raised my attention again!

Every time I start the server (takes about 90 minutes for model construction), only some amount of events is transferred and then I see the above warnings in the log file. I know that much more events have to be transfered, however, it seems like the server stops working somewhere, even if the server process is still running!

The server is configured with 2 network cards, each defined with a fixed IP Adress. I don’t see this behaviour on a server with 2 NIC, 1 with DNS used and the 2nd with fixed address.

Could this cause the error?

Many thanks.

At the moment I use:

// *** Server Endpoints
// the port for the binary protocol
server.setPort(4840);

// add ‘localhost’ to the endpoint list
server.setUseLocalhost(true);

// optional server name part of the URI
server.setServerName(“OpcUa/MyServer”);
// Add the IP address(es) of the server host to the endpoints
server.setUseAllIpAddresses(true);

How can I bind a specific IPAdress or Hostname only?

Thanks. I’ll give it a try. Maybe it changes something…
