> GridDhtPartitionExchangeManager$ExhcangeFutureSet store huge message
> GridDhtPartitionsFullMessage with IgniteDhtPartitionCountersMap2 for each
> cache group with two long[partCount]. If we have big grid (100+ nodes) with
> large amount of cacheGroups and partitions in
> CachePartitionFullCountersMap(long[] initialUpdCntrs; long[] updCntrs;)
> <cacheGroups>*<2 arrays>*<partCount>*<sizeOflong=8> =
> GridDhtPartitionsFullMessage size and we store 1000 of messages in history.
> To reproduce: start few cacheGroup with huge number of partitions with few
> caches and analyze heap dump in Eclipse MAT (for example)
