Dan Berindei commented on ISPN-7884:
------------------------------------

[~rvansa] I'm not sure if it's related, but I've noticed that after a leave, the coordinator sometimes broadcasts a new topology with the same CH and only the actual members changed, and I don't think that's necessary and/or correct. If the cache is not entering degraded mode we're going to broadcast another topology with the leaver removed from the current CH immediately anyway, so all the intermediate topology doesn't buy us anything. On the contrary, any commands that got a `SuspectedException` and were waiting for a new topology to retry will retry too soon, and will get a `SuspectedException` again.

> GetAllCommand in BaseDistributionInterceptor handles all unsuccessful responses by throwing OutdatedTopologyException.
> BaseStateTransferInterceptor assumes that this is due to UnsureResponse in a scenario where it should be possible to retry the command immediately.
> If this occurs due to CacheNotFoundResponse (node being suspected) but before the availability mode is updated/consistent hash is updated with lost segments assigned to other nodes, the command is retried in a loop up to a point where the thread hits stack overflow.
> This does not affect regular cache.get() since this one throws AllOwnersLostException instead and this is treated differently in BaseStateTransferInterceptor.
