> Key: IGNITE-7818
> URL: https://issues.apache.org/jira/browse/IGNITE-7818
> Project: Ignite
> Issue Type: Bug
> Components: persistence
> Reporter: Aleksey Plekhanov
> Assignee: Ivan Fedotov
> Priority: Major
>
> There is an assertion in the method org.apache.ignite.internal.processors.cache.persistence.pagemem.PageMemoryImpl.Segment#removePageForReplacement:
>
> {code:java}
> assert relRmvAddr != INVALID_REL_PTR;{code}
> Which seems potentially dangerous. In some rare cases, when count of interations more then 40% of allocated pages and all processed pages are aquired, the {{relRmvAddr}} variable will be uninitialized and {{AssertionException}} will be thrown. But it's a correct case and page to evict can be found later in the method {{tryToFindSequentially.}}
