>
> Scenario
> 1. Start replicated cache on ignite node, memory region approx 6 Gb, heap 1Gb
> 2. Load significant amount of data to cache with values approx 200Kb (~20K kv
> pairs)
> 3. Start another node
> First node (supplier) will crash while initializing rebalance iterator with
> OOM
> Main reason -- all values, to whon pointed from leaf of BTree, are all loaded
