logs and configuration I used in test 2.

No NPE, but the state of the cache item was different on each node. Number of cache items was correct - 2 as I store session metadata and session data separately.

Everything was ok when I changed numOwners  to be same as number of cluster nodes.

> I am using FineGrainedAtomicMap to store data into clustering distributed cache. When clustering set to replicated  doesn't cause any issues or at least I haven't run
> into any. When I switch to distributed mode I don't see some key,value pairs in some nodes. This happens randomly. The numOwners is set to two and I have cluster of three nodes.
