Maxim Muzafarov commented on IGNITE-10959:
------------------------------------------

Folks,

This issue was completely out of our radar. It's sad to hear that it affects so 
use cases.
I'll try to investigate the issue shortly, right after finishing [IEP-43: 
Cluster 
snapshots|https://cwiki.apache.org/confluence/display/IGNITE/IEP-43%3A+Cluster+snapshots]
 retated tasks.

Will keep you it touch.
