> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 1.7, 1.8
> Reporter: Alexandr Kuramshin
> Assignee: Evgenii Zhuravlev
> Priority: Major
> Labels: easyfix
>
> After GridDhtPartitionsExchangeFuture has been completed,
> GridCachePartitionExchangeManager still stores it in field ExchangeFutureSet
> exchFuts (for race condition handling).
> But many GridDhtPartitionsSingleMessage objects stored in field
> ConcurrentMap<UUID, GridDhtPartitionsAbstractMessage> msgs is not needed
> after the future has been processed.
> This map should be cleared in the end of the method onAllReceived().
