Hi,
Can you please share your cache configuration. How many nodes do you
have in your cluster?
If you are running in PARTITONED mode then some exchange of information
will occur.
More details here: https://apacheignite.readme.io/docs/cache-modes
Do you have a reproducer project?
This message means that you are trying to start two ignite instances in
the same JVM with the same
igniteInstanceName in your configuration.
