> -----------------------------------------------------------------------------
>
> Key: IGNITE-14003
> URL: https://issues.apache.org/jira/browse/IGNITE-14003
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.9, 2.8.1, 2.9.1
> Reporter: Ivan Daschinskiy
> Assignee: Ivan Daschinskiy
> Priority: Critical
> Attachments: ReplicatedCacheRebalanceTest.java
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> 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 to buffer in BPlusTree#ForwardCursor. For replicated cache, 512 iterators for each partition are created at once.
> Reproducer is attached, run it with *-Xmx1G*
