---------------------------------------

Hi Ben,

 

I tried checking the jgroups upgrade to v3.6.19. In RHEL, it works fine i.e., cluster communication is happening without any issues.

And in Windows instance we see the issue(customer communication is not happening for UDP, We don’t see Member joined in logs and we don’t see any specific errors/exceptions also).

 

So do we need to have any additional properties or additional configurations to be done specific to windows to get it worked?

Can you share the sample/example code which is used to test the cluster communication in windows using jgroups 3.6.19 jars?

 

Thanks

Janardhan
