New cluster / channel are failing after 9 are created successfully

Hi,

We are running jgroups 4.2.22.

 Following is the protocols stack.

</config>

I am trying to create 12 channels.

We are creating separate cluster for each channels.
When we are trying to connect a channel, we are assigning it with new cluster name.

Cluster name are consists of channel number, i.e 0, 1, 2, 3.....11.

_channel.setName("Cluster" + "-datachannel_" + channelNumber);
_channel.connect(_connStr);

When we starts application, channel are created up to number 9 only. That means 0, 1, 2, 3...9 are created successfully.

When It try to connect to channel number or cluster number 10, it is throwing exception.

port_range is far more than the number of channel we are creating.

Tried setting different port in bind_port and initial_hosts.

Can you please help us what we are missing here.

How we can resolve it.

Thanks

Thank you so much for the reply and resolution.

That works.

Amazing.

I need one more help.

When I am trying to connect more than one channels we are getting some warning logs.

Attaching image also.

What are they warnings?

Do I need to take care of them?

If yes, how can I resolve this?

Thanks again.

This shows that you have different clusters using the same ports. E.g.
TCPPING.initial_members listing the same IP addresses:ports, or MPING
having the same mcast_addr/mcast_port pairs.

You'll need to have different (discovery) ports for each cluster. The
warnings themselves are not causing any problems, besides cluttering up
the log files.

Thanks for the response.

It worked for us.

Sorry for delay in response.

We are getting some un expected jgroups logs.

Can you please look those and help us what they are and how can we deal with them.

attaching screen shot.

There's nothing unexpected in that log; a member is excluded...
