Galder Zamarreño commented on ISPN-2550:
----------------------------------------

Tomas, seems like the config that you provided works fine as storage only.

Can you create a separate issue to follow your issue? Don't wanna mix with node kill issue.

Also, if you can replicate the issue again and provide JDG version information, TRACE logs...etc? Can you try to replicate the issue on master of JDG too?

> Tomas noticed this a while ago in a specific functional test:

> I'm creating a more general JIRA, cause I'm having this in resilience test.
> What I found by quick debug, is that here:

> It hapens after I kill a node in a resilience test and the exception appears when querying for the node in the members cache.
