[jira] [Commented] (IGNITE-6852) Kill ignite process in case of multithreaded reads cause segmentation fault

    [ https://issues.apache.org/jira/browse/IGNITE-6852?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16247163#comment-16247163 ] 

Alexey Goncharuk commented on IGNITE-6852:
------------------------------------------

The process crashes because a user has live cursor which attempts to iterate the BTree and at the same time memory region is deallocated on node stop.
