look like we clash the same problem on blt change:

> Rebalancing: IgniteConfiguration.rebalanceThreadPoolSize is wrongly treated
> ---------------------------------------------------------------------------

> Key: IGNITE-3195
> URL: https://issues.apache.org/jira/browse/IGNITE-3195
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Reporter: Denis Magda
> Assignee: Anton Vinogradov
> Priority: Major
> Labels: iep-16
> Fix For: 2.8
>
> Time Spent: 10m
> Remaining Estimate: 0h

> Presently it's considered that the maximum number of threads that has to process all demand and supply messages coming from all the nodes must not be bigger than {{IgniteConfiguration.rebalanceThreadPoolSize}}.
> Current implementation relies on ordered messages functionality creating a number of topics equal to {{IgniteConfiguration.rebalanceThreadPoolSize}}.
> However, the implementation doesn't take into account that ordered messages, that correspond to a particular topic, are processed in parallel for different nodes. Refer to the implementation of {{GridIoManager.processOrderedMessage}} to see that for every topic there will be a unique {{GridCommunicationMessageSet}} for every node.
> Also to prove that this is true you can refer to this execution stack

> All this means that in fact the number of threads that will be busy with replication activity will be equal to {{IgniteConfiguration.rebalanceThreadPoolSize}} x number_of_nodes_participated_in_rebalancing
