>             Project: Ignite

>
> In {{GridDhtPartitionsExchangeFuture#onNodeLeft}} we have the following code:
> {code}
> if (!srvNodes.remove(node)
>     return;
> {code}
> The issue is that the {{srvNodes}} collection is created when partition exchange future is initialized. After the exchange future is merged, we will wait for more nodes to respond. However, since those nodes never added to {{srvNodes}}, the event will never be processed and the exchange future will hang.
