Ivan Rakov commented on IGNITE-12412:
-------------------------------------
[~agoncharuk] Looks good.
Please split your patch into two commits (fix itself and refactoring) and merge
them separately - it would simplify further fix porting.
> 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
> Time Spent: 1h 10m
> Remaining Estimate: 0h
>
> 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.
