Summary: 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 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
