Subject [jira] [Commented] (IGNITE-12042) Atempt to remove entries from fully populated data region may result in IgineOutOfMemoryException
Date Tue, 06 Aug 2019 15:31:00 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-12042?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16901186#comment-16901186

Pavel Pereslegin commented on IGNITE-12042:
-------------------------------------------

[~slava.koptilin],
_totalPages <  datarowPages + linkPages + *nonEmptyPages* + additionalPages_
I don't see in PR (+nonEmptyPages), I just see linkPages:
{{(nonEmptyPages * (8.0 / pageMem.pageSize() + 1)* 1.5}}

Or I still missing something? :)
