-----------------------------------------
Summary: Incorrect assertion in PDS page eviction method
Key: IGNITE-7818
URL: https://issues.apache.org/jira/browse/IGNITE-7818
Project: Ignite
Issue Type: Bug
Reporter: Aleksey Plekhanov
There is 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.}}
