Alexey Goncharuk updated IGNITE-12412:
--------------------------------------
Ignite Flags: Release Notes Required (was: Docs Required,Release Notes
Required)
> Incomplete check for ABA problem in PageMemoryImpl#PagePool
> -----------------------------------------------------------
>
> Key: IGNITE-12412
> URL: https://issues.apache.org/jira/browse/IGNITE-12412
> Project: Ignite
> Issue Type: Improvement
> Reporter: Alexey Goncharuk
> Assignee: Alexey Goncharuk
> Priority: Critical
>
> In current implementation, {{PagePool#releasePage}} clears the counter part
> of the returned page ID, which effectively disables the ABA check intended in
> the class. This issue can be rarely reproduced on zOS during checkpoints
> (when pages are being taken and returned to the checkpoint pages pool).
> I managed to write a unit-test to reproduce this issue on x86.
