> URL: https://issues.apache.org/jira/browse/IGNITE-9445
> Project: Ignite
> Issue Type: Bug
> Reporter: Alexei Scherbakov
> Assignee: Alexei Scherbakov
> Priority: Major
>
> The problem arises when passing pageId with not actual page rotation tag to org.apache.ignite.internal.processors.cache.persistence.pagemem.PageMemoryImpl#acquirePage(int, long, boolean).
> It's not possible in advance to know the actual value without reading stored page.
> Such scenario may lead to locked forever page if passed and persisted tags are different.
> Solution - unlock the page using actual(persisted) tag value.
