[jira] [Created] (IGNITE-7818) Incorrect assertion in PDS page eviction method

Aleksey Plekhanov created IGNITE-7818:
-----------------------------------------

             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.}}
